Debian DLA-657-1 : libarchive security update

high Nessus Plugin ID 94077

Language:

Synopsis

The remote Debian host is missing a security update.

Description

It was found that libarchive mishandled hardlink archive entries of non-zero data size, possibly allowing remote attackers to to write to arbitrary files via especially crafted archives.

For Debian 7 'Wheezy', these problems have been fixed in version 3.0.4-3+wheezy4.

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.
