Package : librpcsecgss
Vulnerability : buffer overflow
Problem type : remote
Debian-specific: no
CVE ID : CVE-2007-4743

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 librpcseggss
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.
