Debian DLA-2095-1 : storebackup security update

high Nessus Plugin ID 133509

Language:

Synopsis

The remote Debian host is missing a security update.

Description

storeBackup.pl in storeBackup through 3.5 relies on the /tmp/storeBackup.lock pathname, which allows symlink attacks that possibly lead to privilege escalation.

Local users can also create a plain file named /tmp/storeBackup.lock to block use of storeBackup until an admin manually deletes that file.

For Debian 8 'Jessie', this problem has been fixed in version 3.2.1-1+deb8u1.

We recommend that you upgrade your storebackup 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 storebackup package.
