Several local vulnerabilities have been discovered in the PAM module for MIT Kerberos. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2009-0360     Russ Allbery discovered that the Kerberos PAM module     parsed configuration settings from environment variables     when run from a setuid context. This could lead to local     privilege escalation if an attacker points a setuid     program using PAM authentication to a Kerberos setup     under her control.

  - CVE-2009-0361     Derek Chan discovered that the Kerberos PAM module     allows reinitialisation of user credentials when run     from a setuid context, resulting in potential local     denial of service by overwriting the credential cache     file or to privilege escalation.

The remote host is affected by the vulnerability described in GLSA-200903-39 (pam_krb5: Privilege escalation)

    The following vulnerabilities were discovered:
    pam_krb5     does not properly initialize the Kerberos libraries for setuid use     (CVE-2009-0360).
    Derek Chan reported that calls to     pam_setcred() are not properly handled when running setuid     (CVE-2009-0361).
  Impact :

    A local attacker could set an environment variable to point to a     specially crafted Kerberos configuration file and launch a PAM-based     setuid application to elevate privileges, or change ownership and     overwrite arbitrary files.
  Workaround :

    There is no known workaround at this time.

It was discovered that pam_krb5 parsed environment variables when run with setuid applications. A local attacker could exploit this flaw to bypass authentication checks and gain root privileges. (CVE-2009-0360)

Derek Chan discovered that pam_krb5 incorrectly handled refreshing existing credentials when used with setuid applications. A local attacker could exploit this to create or overwrite arbitrary files, and possibly gain root privileges. (CVE-2009-0361).

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

Derek Chan discovered that the PAM module for the Heimdal Kerberos implementation allows reinitialisation of user credentials when run from a setuid context, resulting in potential local denial of service by overwriting the credential cache file or to local privilege escalation.
