Package : libtasn1-2
Vulnerability : buffer overflows
Problem type : remote
Debian-specific: no
CVE ID : CVE-2006-0645
Bugtraq ID : 16568

Evgeny Legerov discovered several out-of-bounds memory accesses in the
DER decoding component component of the Tiny ASN.1 Library that allows
attackers to crash the DER decoder and possibly execute arbitrary code.

The old stable distribution (woody) is not affected by these problems.

For the stable distribution (sarge) these problems have been fixed in
version 2_0.2.10-3sarge1.

For the unstable distribution (sid) these problems will be fixed soon.

We recommend that you upgrade your gnutls packages.
