Detail
| Problem Description: An updated pam_krb5 package that fixes a security issue is now available for Red Hat Enterprise Linux 5. This update has been rated as having moderate security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64 3. Description: The pam_krb5 module allows Pluggable Authentication Modules (PAM) aware applications to use Kerberos to verify user identities by obtaining user credentials at log in time. A flaw was found in the pam_krb5 "existing_ticket" configuration option. If a system is configured to use an existing credential cache via the "existing_ticket" option, it may be possible for a local user to gain elevated privileges by using a different, local user's credential cache. (CVE-2008-3825) Red Hat would like to thank Stéphane Bertin for responsibly disclosing this issue. Users of pam_krb5 should upgrade to this updated package, which contains a backported patch to resolve this issue. 4. Solution: Before applying this update, make sure that all previously-released errata relevant to your system have been applied. This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at http://kbase.redhat.com/faq/FAQ_58_10188 5. Bugs fixed (http://bugzilla.redhat.com/): 461960 - CVE-2008-3825 pam_krb5 existing_ticket permission flaw |
