(RHSA-2005:012) krb5 security update

Kerberos is a networked authentication system that uses a trusted third
party (a KDC) to authenticate clients and servers to each other.

A heap based buffer overflow bug was found in the administration library of
Kerberos 1.3.5 and earlier. This bug could allow an authenticated remote
attacker to execute arbitrary commands on a realm’s master Kerberos KDC.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2004-1189 to this issue.

Additionally a temporary file bug was found in the Kerberos krb5-send-pr
program. It is possible that an attacker could create a temporary file
that would allow an arbitrary file to be overwritten which the victim has
write access to. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2004-0971 to this issue.

All users of krb5 should upgrade to these updated packages, which contain
backported security patches to resolve these issues.
