Debian DLA-188-1 : arj security update

High Nessus Plugin ID 82645

Synopsis

The remote Debian host is missing a security update.

Description

Multiple vulnerabilities have been discovered in arj, an open source version of the arj archiver. The Common Vulnerabilities and Exposures project identifies the following problems :

CVE-2015-0556

Jakub Wilk discovered that arj follows symlinks created during unpacking of an arj archive. A remote attacker could use this flaw to perform a directory traversal attack if a user or automated system were tricked into processing a specially crafted arj archive.

CVE-2015-0557

Jakub Wilk discovered that arj does not sufficiently protect from directory traversal while unpacking an arj archive containing file paths with multiple leading slashes. A remote attacker could use this flaw to write to arbitrary files if a user or automated system were tricked into processing a specially crafted arj archive.

CVE-2015-2782

Jakub Wilk and Guillem Jover discovered a buffer overflow vulnerability in arj. A remote attacker could use this flaw to cause an application crash or, possibly, execute arbitrary code with the privileges of the user running arj.

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 arj package.
