Synopsis :

The remote Ubuntu host is missing a security-related patch.

Description :

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.
