Multiple buffer overflows in the gd graphics library (libgd) 2.0.21 and earlier may allow remote attackers to execute arbitrary code via malformed image files that trigger the overflows due to improper calls to the gdMalloc function. One instance in gd_io_dp.c does not appear to be corrected in the embedded copy of GD used in php to build the php-gd package. (CVE-2004-0941)

Integer overflows were reported in the GD Graphics Library (libgd) 2.0.28, and possibly other versions. These overflows allow remote attackers to cause a denial of service and possibly execute arbitrary code via PNG image files with large image rows values that lead to a heap-based buffer overflow in the gdImageCreateFromPngCtx() function.
PHP, as packaged in Mandriva Linux, contains an embedded copy of the GD library, used to build the php-gd package. (CVE-2004-0990)

The c-client library 2000, 2001, or 2004 for PHP 3.x, 4.x, and 5.x, when used in applications that accept user-controlled input for the mailbox argument to the imap_open function, allow remote attackers to obtain access to an IMAP stream data structure and conduct unauthorized IMAP actions. (CVE-2006-1017)

Integer overflow in the wordwrap function in string.c in might allow context-dependent attackers to execute arbitrary code via certain long arguments that cause a small buffer to be allocated, which triggers a heap-based buffer overflow in a memcpy function call, a different vulnerability than CVE-2002-1396. (CVE-2006-1990) The previous update for this issue did not resolve the issue on 64bit platforms.

The cURL library (libcurl) in PHP 4.4.2 and 5.1.4 allows attackers to bypass safe mode and read files via a file:// request containing nul characters. (CVE-2006-2563)

Buffer consumption vulnerability in the tempnam function in PHP 5.1.4 and 4.x before 4.4.3 allows local users to bypass restrictions and create PHP files with fixed names in other directories via a pathname argument longer than MAXPATHLEN, which prevents a unique string from being appended to the filename. (CVE-2006-2660)

The LZW decoding in the gdImageCreateFromGifPtr function in the Thomas Boutell graphics draw (GD) library (aka libgd) 2.0.33 allows remote attackers to cause a denial of service (CPU consumption) via malformed GIF data that causes an infinite loop. PHP, as packaged in Mandriva Linux, contains an embedded copy of the GD library, used to build the php-gd package. (CVE-2006-2906)

The error_log function in PHP allows local users to bypass safe mode and open_basedir restrictions via a 'php://' or other scheme in the third argument, which disables safe mode. (CVE-2006-3011)

An unspecified vulnerability in session.c in PHP before 5.1.3 has unknown impact and attack vectors, related to 'certain characters in session names', including special characters that are frequently associated with CRLF injection, SQL injection, and cross-site scripting (XSS) vulnerabilities. NOTE: while the nature of the vulnerability is unspecified, it is likely that this is related to a violation of an expectation by PHP applications that the session name is alphanumeric, as implied in the PHP manual for session_name().
(CVE-2006-3016)

An unspecified vulnerability in PHP before 5.1.3 can prevent a variable from being unset even when the unset function is called, which might cause the variable's value to be used in security-relevant operations. (CVE-2006-3017)

An unspecified vulnerability in the session extension functionality in PHP before 5.1.3 has unkown impact and attack vectors related to heap corruption. (CVE-2006-3018)

Multiple heap-based buffer overflows in the (1) str_repeat and (2) wordwrap functions in ext/standard/string.c in PHP before 5.1.5, when used on a 64-bit system, have unspecified impact and attack vectors, a different vulnerability than CVE-2006-1990. (CVE-2006-4482)

The cURL extension files (1) ext/curl/interface.c and (2) ext/curl/streams.c in PHP before 5.1.5 permit the CURLOPT_FOLLOWLOCATION option when open_basedir or safe_mode is enabled, which allows attackers to perform unauthorized actions, possibly related to the realpath cache. (CVE-2006-4483)

Unspecified vulnerability in PHP before 5.1.6, when running on a 64-bit system, has unknown impact and attack vectors related to the memory_limit restriction. (CVE-2006-4486)

The GD related issues (CVE-2004-0941, CVE-2004-0990, CVE-2006-2906) affect only Corporate 3 and Mandrake Network Firewall 2.

The php-curl issues (CVE-2006-2563, CVE-2006-4483) affect only Mandriva 2006.0.

Updated packages have been patched to address all these issues. Once these packages have been installed, you will need to restart Apache (service httpd restart) in order for the changes to take effect.

According to its banner, the version of PHP installed on the remote host is older than 4.4.4.  As such, it is potentially affected by the following vulnerabilities :

    (CVE-2006-1017)

  - A buffer overflow exists in the sscanf function.
    (CVE-2006-4020)

According to its banner, the version of PHP 5.x installed on the remote host is older than 5.1.5.  Such versions may be affected by the following vulnerabilities :

    (CVE-2006-1017)

  - A buffer overflow exists in the sscanf function.
    (CVE-2006-4020)
