Debian DSA-3289-1 : p7zip - security update

medium Nessus Plugin ID 84200

Language:

Synopsis

The remote Debian host is missing a security-related 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.

Solution

Upgrade the p7zip packages.

For the oldstable distribution (wheezy), this problem has been fixed in version 9.20.1~dfsg.1-4+deb7u1.

For the stable distribution (jessie), this problem has been fixed in version 9.20.1~dfsg.1-4.1+deb8u1.
