Debian DLA-510-1 : p7zip security update

high Nessus Plugin ID 91574

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Marcin 'Icewall' Noga of Cisco Talos discovered an out-of-bound read vulnerability in the CInArchive::ReadFileItem method in p7zip, a 7zr file archiver with high compression ratio. A remote attacker can take advantage of this flaw to cause a denial of service or, potentially the execution of arbitrary code with the privileges of the user running p7zip, if a specially crafted UDF file is processed.

For Debian 7 'Wheezy', these problems have been fixed in version 9.20.1~dfsg.1-4+deb7u2.

We recommend that you upgrade your p7zip 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 p7zip, and p7zip-full packages.
