Debian DSA-3599-1 : p7zip - security update

high Nessus Plugin ID 91549

Language:

Synopsis

The remote Debian host is missing a security-related 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.

Solution

Upgrade the p7zip packages.

For the stable distribution (jessie), this problem has been fixed in version 9.20.1~dfsg.1-4.1+deb8u2.
