SynopsisThe remote Ubuntu host is missing a security-related patch.
DescriptionIt 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.
SolutionUpdate the affected libpam-krb5 package.
