Debian DSA-5203-1 : gnutls28 - security update

high Nessus Plugin ID 163927

Language:

Synopsis

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

Description

The remote Debian 11 host has packages installed that are affected by a vulnerability as referenced in the dsa-5203 advisory.

Jaak Ristioja discovered a double-free vulnerability in GnuTLS, a library implementing the TLS and SSL protocols, during verification of pkcs7 signatures. A remote attacker can take advantage of this flaw to cause an application using the GnuTLS library to crash (denial of service), or potentially, to execute arbitrary code. For the stable distribution (bullseye), this problem has been fixed in version 3.7.1-5+deb11u2. We recommend that you upgrade your gnutls28 packages. For the detailed security status of gnutls28 please refer to its security tracker page at: https://security- tracker.debian.org/tracker/gnutls28

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the gnutls28 packages.

For the stable distribution (bullseye), this problem has been fixed in version 3.7.1-5+deb11u2.
