Debian DLA-617-1 : libarchive security update

medium Nessus Plugin ID 93415

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Several security vulnerabilities have been discovered in libarchive, a multi-format archive and compression library. An attacker could take advantage of these flaws to cause an out of bounds read or a denial of service against an application using the libarchive12 library using a carefully crafted input file.

CVE-2015-8915

Paris Zoumpouloglou of Project Zero labs discovered a flaw in libarchive bsdtar. Using a crafted file bsdtar can perform an out-of-bounds memory read which will lead to a SEGFAULT.

CVE-2016-7166

Alexander Cherepanov discovered a flaw in libarchive compression handling. Using a crafted gzip file, one can get libarchive to invoke an infinite chain of gzip compressors until all the memory has been exhausted or another resource limit kicks in.

For Debian 7 'Wheezy', these problems have been fixed in version 3.0.4-3+wheezy3.

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.
