Debian DLA-2212-1 : openconnect security update

critical Nessus Plugin ID 136673

Language:

Synopsis

The remote Debian host is missing a security update.

Description

OpenConnect, a VPN software, had a buffer overflow, causing a denial of service (application crash) or possibly unspecified other impact, via crafted certificate data to get_cert_name in gnutls.c.

For Debian 8 'Jessie', this problem has been fixed in version 6.00-2+deb8u2.

We recommend that you upgrade your openconnect packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
