Vulnerable:

Yes

Security database references:

In Mitre's CVE dictionary: CVE-2007-4743.

More information:

It has been discovered that the original patch for a buffer overflow in svc_auth_gss.c in the RPCSEC_GSS RPC library in MIT Kerberos 5 (CVE-2007-3999, DSA-1368-1) was insufficient to protect from arbitrary code execution in some environments.

The old stable distribution (sarge) does not contain a librpcsecgss package.

For the stable distribution (etch), this problem has been fixed in version 0.14-2etch3.

For the unstable distribution (sid), this problem has been fixed in version 0.14-4.

We recommend that you upgrade your librpcsecgss package.

Fixed in:

Debian GNU/Linux 4.0 (etch)
