-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - ------------------------------------------------------------------------ Debian Security Advisory DSA-1721-1 security@debian.org http://www.debian.org/security/ Moritz Muehlenhoff February 11, 2009 http://www.debian.org/security/faq - ------------------------------------------------------------------------ Package : libpam-krb5 Vulnerability : several Problem type : local Debian-specific: no CVE Id(s) : CVE-2009-0360 CVE-2009-0361 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.
