New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

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.
