According to its self-reported version number, the Apache Tomcat server listening on the remote host is prior to 4.1.40, 5.5.28, or 6.0.20. It is, therefore, affected by the following vulnerabilities :

  - The remote server is affected by a directory traversal     vulnerability if a RequestDispatcher obtained from a     Request object is used. A specially crafted value for a     request parameter can be used to access potentially     sensitive configuration files or other files, e.g.,     files in the WEB-INF directory. (CVE-2008-5515)

  - The remote server is affected by a denial of service     vulnerability if configured to use the Java AJP     connector. An attacker can send a malicious request with     invalid headers which causes the AJP connector to be put     into an error state for a short time. This behavior can     be used as a denial of service attack. (CVE-2009-0033)

  - The remote server is affected by a username enumeration     vulnerability if configured to use FORM authentication     along with the 'MemoryRealm', 'DataSourceRealm', or     'JDBCRealm' authentication realms. (CVE-2009-0580)

  - The remote server is affected by a script injection     vulnerability if the example JSP application,     'cal2.jsp', is installed. An unauthenticated, remote     attacker can exploit this issue to inject arbitrary HTML     or script code into a user's browser to be executed     within the security context of the affected site.
    (CVE-2009-0781)

  - The remote server is vulnerable to unauthorized     modification of 'web.xml', 'context.xml', or TLD files     of arbitrary web applications. This vulnerability allows     the XML parser, used to process the XML and TLD files,     to be replaced. (CVE-2009-0783)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

This update of tomcat fixes several vulnerabilities :

  - CVE-2008-5515: RequestDispatcher usage can lead to     information leakage

  - CVE-2009-0033: denial of service via AJP connection

  - CVE-2009-0580: some authentication classes allow user     enumeration

  - CVE-2009-0781: XSS bug in example application cal2.jsp

  - CVE-2009-0783: replacing XML parser leads to information     leakage Additionally, non-security bugs were fixed.

The remote Redhat Enterprise Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2009:1164 advisory.

    Apache Tomcat is a servlet container for the Java Servlet and JavaServer     Pages (JSP) technologies.

    It was discovered that the Red Hat Security Advisory RHSA-2007:0871 did not     address all possible flaws in the way Tomcat handles certain characters and     character sequences in cookie values. A remote attacker could use this flaw     to obtain sensitive information, such as session IDs, and then use this     information for session hijacking attacks. (CVE-2007-5333)

    Note: The fix for the CVE-2007-5333 flaw changes the default cookie     processing behavior: with this update, version 0 cookies that contain     values that must be quoted to be valid are automatically changed to version     1 cookies. To reactivate the previous, but insecure behavior, add the     following entry to the /etc/tomcat5/catalina.properties file:

    org.apache.tomcat.util.http.ServerCookie.VERSION_SWITCH=false

    It was discovered that request dispatchers did not properly normalize user     requests that have trailing query strings, allowing remote attackers to     send specially-crafted requests that would cause an information leak.
    (CVE-2008-5515)

    A flaw was found in the way the Tomcat AJP (Apache JServ Protocol)     connector processes AJP connections. An attacker could use this flaw to     send specially-crafted requests that would cause a temporary denial of     service. (CVE-2009-0033)

    It was discovered that the error checking methods of certain authentication     classes did not have sufficient error checking, allowing remote attackers     to enumerate (via brute force methods) usernames registered with     applications running on Tomcat when FORM-based authentication was used.
    (CVE-2009-0580)

    A cross-site scripting (XSS) flaw was found in the examples calendar     application. With some web browsers, remote attackers could use this flaw     to inject arbitrary web script or HTML via the time parameter.
    (CVE-2009-0781)

    It was discovered that web applications containing their own XML parsers     could replace the XML parser Tomcat uses to parse configuration files. A     malicious web application running on a Tomcat instance could read or,     potentially, modify the configuration and XML-based data of other web     applications deployed on the same Tomcat instance. (CVE-2009-0783)

    Users of Tomcat should upgrade to these updated packages, which contain     backported patches to resolve these issues. Tomcat must be restarted for     this update to take effect.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Updated tomcat5 packages that fix multiple security issues are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

Apache Tomcat is a servlet container for the Java Servlet and JavaServer Pages (JSP) technologies.

A flaw was found in the way Tomcat handled the Transfer-Encoding header in HTTP requests. A specially crafted HTTP request could prevent Tomcat from sending replies, or cause Tomcat to return truncated replies, or replies containing data related to the requests of other users, for all subsequent HTTP requests. (CVE-2010-2227)

The Tomcat security update RHSA-2009:1164 did not, unlike the erratum text stated, provide a fix for CVE-2009-0781, a cross-site scripting (XSS) flaw in the examples calendar application. With some web browsers, remote attackers could use this flaw to inject arbitrary web script or HTML via the 'time' parameter. (CVE-2009-2696)

Two directory traversal flaws were found in the Tomcat deployment process. A specially crafted WAR file could, when deployed, cause a file to be created outside of the web root into any directory writable by the Tomcat user, or could lead to the deletion of files in the Tomcat host's work directory. (CVE-2009-2693, CVE-2009-2902)

Users of Tomcat should upgrade to these updated packages, which contain backported patches to resolve these issues. Tomcat must be restarted for this update to take effect.

Fix for CVE-2008-5515, CVE-2009-0033, CVE-2009-0580, CVE-2009-0781, and CVE-2009-0783.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Multiple security vulnerabilities has been identified and fixed in tomcat5 :

Apache Tomcat 4.1.0 through 4.1.39, 5.5.0 through 5.5.27, 6.0.0 through 6.0.18, and possibly earlier versions normalizes the target pathname before filtering the query string when using the RequestDispatcher method, which allows remote attackers to bypass intended access restrictions and conduct directory traversal attacks via .. (dot dot) sequences and the WEB-INF directory in a Request (CVE-2008-5515).

Apache Tomcat 4.1.0 through 4.1.39, 5.5.0 through 5.5.27, and 6.0.0 through 6.0.18, when the Java AJP connector and mod_jk load balancing are used, allows remote attackers to cause a denial of service (application outage) via a crafted request with invalid headers, related to temporary blocking of connectors that have encountered errors, as demonstrated by an error involving a malformed HTTP Host header (CVE-2009-0033).

Apache Tomcat 4.1.0 through 4.1.39, 5.5.0 through 5.5.27, and 6.0.0 through 6.0.18, when FORM authentication is used, allows remote attackers to enumerate valid usernames via requests to /j_security_check with malformed URL encoding of passwords, related to improper error checking in the (1) MemoryRealm, (2) DataSourceRealm, and (3) JDBCRealm authentication realms, as demonstrated by a % (percent) value for the j_password parameter (CVE-2009-0580).

The calendar application in the examples web application contains an XSS flaw due to invalid HTML which renders the XSS filtering protection ineffective (CVE-2009-0781).

Apache Tomcat 4.1.0 through 4.1.39, 5.5.0 through 5.5.27, and 6.0.0 through 6.0.18 permits web applications to replace an XML parser used for other web applications, which allows local users to read or modify the (1) web.xml, (2) context.xml, or (3) tld files of arbitrary web applications via a crafted application that is loaded earlier than the target application (CVE-2009-0783).

The updated packages have been patched to prevent this. Additionally Apache Tomcat has been upgraded to the latest 5.5.27 version for 2009.0.

  c. Third-party library update for ntp.
   The Network Time Protocol (NTP) is used to synchronize a computer's   time with a referenced time source.
   ESXi 3.5 and ESXi 4.0 have a ntp client that is affected by the   following security issue. Note that the same security issue is   present in the ESX Service Console as described in section d. of   this advisory.
   A buffer overflow flaw was discovered in the ntpd daemon's NTPv4   authentication code. If ntpd was configured to use public key   cryptography for NTP packet authentication, a remote attacker could   use this flaw to send a specially crafted request packet that could   crash ntpd or, potentially, execute arbitrary code with the   privileges of the 'ntp' user.
   The Common Vulnerabilities and Exposures Project (cve.mitre.org)   has assigned the name CVE-2009-1252 to this issue.
   The NTP security issue identified by CVE-2009-0159 is not relevant   for ESXi 3.5 and ESXi 4.0.
 d. Service Console update for ntp

  Service Console package ntp updated to version ntp-4.2.2pl-9el5_3.2    The Network Time Protocol (NTP) is used to synchronize a computer's   time with a referenced time source.
   The Service Console present in ESX is affected by the following   security issues.
   A buffer overflow flaw was discovered in the ntpd daemon's NTPv4   authentication code. If ntpd was configured to use public key   cryptography for NTP packet authentication, a remote attacker could   use this flaw to send a specially crafted request packet that could   crash ntpd or, potentially, execute arbitrary code with the   privileges of the 'ntp' user.
   NTP authentication is not enabled by default on the Service Console.
   The Common Vulnerabilities and Exposures Project (cve.mitre.org)   has assigned the name CVE-2009-1252 to this issue.
   A buffer overflow flaw was found in the ntpq diagnostic command. A   malicious, remote server could send a specially crafted reply to an   ntpq request that could crash ntpq or, potentially, execute   arbitrary code with the privileges of the user running the ntpq   command.
   The Common Vulnerabilities and Exposures Project (cve.mitre.org)   has assigned the name CVE-2009-0159 to this issue.

 f. Updated Service Console package python

  Service Console package Python update to version 2.4.3-24.el5.

  When the assert() system call was disabled, an input sanitization   flaw was revealed in the Python string object implementation that   led to a buffer overflow. The missing check for negative size values   meant the Python memory allocator could allocate less memory than   expected. This could result in arbitrary code execution with the   Python interpreter's privileges.

  Multiple buffer and integer overflow flaws were found in the Python   Unicode string processing and in the Python Unicode and string   object implementations. An attacker could use these flaws to cause   a denial of service.

  Multiple integer overflow flaws were found in the Python imageop   module. If a Python application used the imageop module to   process untrusted images, it could cause the application to   disclose sensitive information, crash or, potentially, execute   arbitrary code with the Python interpreter's privileges.

  Multiple integer underflow and overflow flaws were found in the   Python snprintf() wrapper implementation. An attacker could use   these flaws to cause a denial of service (memory corruption).

  Multiple integer overflow flaws were found in various Python   modules. An attacker could use these flaws to cause a denial of   service.

  An integer signedness error, leading to a buffer overflow, was   found in the Python zlib extension module. If a Python application   requested the negative byte count be flushed for a decompression   stream, it could cause the application to crash or, potentially,   execute arbitrary code with the Python interpreter's privileges.

  A flaw was discovered in the strxfrm() function of the Python   locale module. Strings generated by this function were not properly   NULL-terminated, which could possibly cause disclosure of data   stored in the memory of a Python application using this function.

  The Common Vulnerabilities and Exposures project (cve.mitre.org)   has assigned the names CVE-2007-2052 CVE-2007-4965 CVE-2008-1721   CVE-2008-1887 CVE-2008-2315 CVE-2008-3142 CVE-2008-3143   CVE-2008-3144 CVE-2008-4864 CVE-2008-5031 to these issues.

 g. Updated Service Console package bind

  Service Console package bind updated to version 9.3.6-4.P1.el5

  The Berkeley Internet Name Domain (BIND) is an implementation of the   Domain Name System (DNS) protocols. BIND includes a DNS server   (named); a resolver library (routines for applications to use when   interfacing with DNS); and tools for verifying that the DNS server   is operating correctly.

  A flaw was found in the way BIND handles dynamic update message   packets containing the 'ANY' record type. A remote attacker could   use this flaw to send a specially crafted dynamic update packet   that could cause named to exit with an assertion failure.

  The Common Vulnerabilities and Exposures project (cve.mitre.org)   has assigned the name CVE-2009-0696 to this issue.

 h. Updated Service Console package libxml2

  Service Console package libxml2 updated to version 2.6.26-2.1.2.8.

  libxml is a library for parsing and manipulating XML files. A   Document Type Definition (DTD) defines the legal syntax (and also   which elements can be used) for certain types of files, such as XML   files.

  A stack overflow flaw was found in the way libxml processes the   root XML document element definition in a DTD. A remote attacker   could provide a specially crafted XML file, which once opened by a   local, unsuspecting user, would lead to denial of service.

  Multiple use-after-free flaws were found in the way libxml parses   the Notation and Enumeration attribute types. A remote attacker   could provide a specially crafted XML file, which once opened by a   local, unsuspecting user, would lead to denial of service.

  The Common Vulnerabilities and Exposures project (cve.mitre.org)   has assigned the names CVE-2009-2414 and CVE-2009-2416 to these   issues.

 i. Updated Service Console package curl

  Service Console package curl updated to version 7.15.5-2.1.el5_3.5

  A cURL is affected by the previously published 'null prefix attack',   caused by incorrect handling of NULL characters in X.509   certificates. If an attacker is able to get a carefully-crafted   certificate signed by a trusted Certificate Authority, the attacker   could use the certificate during a man-in-the-middle attack and   potentially confuse cURL into accepting it by mistake.

  The Common Vulnerabilities and Exposures project (cve.mitre.org)   has assigned the name CVE-2009-2417 to this issue

 j. Updated Service Console package gnutls

  Service Console package gnutil updated to version 1.4.1-3.el5_3.5

  A flaw was discovered in the way GnuTLS handles NULL characters in   certain fields of X.509 certificates. If an attacker is able to get   a carefully-crafted certificate signed by a Certificate Authority   trusted by an application using GnuTLS, the attacker could use the   certificate during a man-in-the-middle attack and potentially   confuse the application into accepting it by mistake.

  The Common Vulnerabilities and Exposures project (cve.mitre.org)   has assigned the name CVE-2009-2730 to this issue
