Debian DSA-2866-1 : gnutls26 - certificate verification flaw

medium Nessus Plugin ID 72647

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

Suman Jana reported that GnuTLS, deviating from the documented behavior, considers a version 1 intermediate certificate as a CA certificate by default.

The oldstable distribution (squeeze) is not affected by this problem as X.509 version 1 trusted CA certificates are not allowed by default.

Solution

Upgrade the gnutls26 packages.

For the stable distribution (wheezy), this problem has been fixed in version 2.12.20-8.
