Debian DLA-1612-1 : libarchive security update

high Nessus Plugin ID 119847
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Debian host is missing a security update.

Description

Daniel Axtens discovered a double-free and use-after-free vulnerability in libarchive's RAR decoder that can result in a denial of service (application crash) or may have other unspecified impact when a malformed RAR archive is processed.

For Debian 8 'Jessie', these problems have been fixed in version 3.1.2-11+deb8u6.

We recommend that you upgrade your libarchive 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.
