Debian DLA-245-1 : p7zip security update

medium Nessus Plugin ID 84166

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Alexander Cherepanov discovered that p7zip is susceptible to a directory traversal vulnerability. While extracting an archive, it will extract symlinks and then follow them if they are referenced in further entries. This can be exploited by a rogue archive to write files outside the current directory.

For the oldoldstable distribution (squeeze), this problem has been fixed in version 9.04~dfsg.1-1+deb6u1.

For the oldstable distribution (wheezy) and stable distribution (jessie), this problem will be fixed soon.

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.
