Debian DSA-3702-1 : tar - security update

high Nessus Plugin ID 94456

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

Harry Sintonen discovered that GNU tar does not properly handle member names containing '..', thus allowing an attacker to bypass the path names specified on the command line and replace files and directories in the target directory.

Solution

Upgrade the tar packages.

For the stable distribution (jessie), this problem has been fixed in version 1.27.1-2+deb8u1.
