Package : libapache-mod-auth-kerb
Vulnerability : heap overflow
Problem type : remote
Debian-specific: no
CVE Id(s) : CVE-2006-5989
BugTraq ID : 21214
Debian Bug : 400589

An off-by-one error leading to a heap-based buffer overflow has been
identified in libapache-mod-auth-kerb, an Apache module for Kerberos
authentication. The error could allow an attacker to trigger an
application crash or potentially execute arbitrary code by sending a
specially crafted kerberos message.

For the stable distribution (sarge), this problem has been fixed in
version 4.996-5.0-rc6-1sarge1.

For the unstable version (sid) and the forthcoming stable version
(etch), this problem has been fixed in version 5.3-1.

We recommend that you upgrade your libapache-mod-auth-kerb package.

Upgrade instructions
- --------------------
