tag_insight = "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 enviromnent 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.

For the stable distribution (etch), these problems have been fixed in
version 2.6-1etch1.

For the upcoming stable distribution (lenny), these problems have been
fixed in version 3.11-4.

For the unstable distribution (sid), these problems will be fixed soon.

We recommend that you upgrade your libpam-krb5 package.";
