Package : krb5
Vulnerability : buffer overflow
Problem-Type : remote
Debian-specific: no
CVE ID : CVE-2007-3999

It was discovered that a buffer overflow of the RPC library of the MIT
Kerberos reference implementation allows the execution of arbitrary code.

The oldstable distribution (sarge) is not affected by this problem.

For the stable distribution (etch) this problem has been fixed in
version 1.4.4-7etch3.

For the unstable distribution (sid) this problem has been fixed in
version 1.6.dfsg.1-7.

We recommend that you upgrade your Kerberos packages.
