Package        : gnutls11
Vulnerability  : cryptographic weakness
Problem-Type   : local
Debian-specific: no
CVE ID         : CVE-2006-4790

Daniel Bleichenbacher discovered a flaw in GNU TLS cryptographic package
that could allow an attacker to generate a forged signature that GNU TLS
will accept as valid.

For the stable distribution (sarge) this problem has been fixed in
version 1.0.16-13.2sarge2.

The unstable distribution (sid) does no longer contain gnutls11, for
gnutls13 this problem has been fixed in version 1.4.4-1.

We recommend that you upgrade your GNU TLS package.
