Debian DLA-978-1 : perl security update

medium Nessus Plugin ID 100624

Language:

Synopsis

The remote Debian host is missing a security update.

Description

The cPanel Security Team reported a time of check to time of use (TOCTTOU) race condition flaw in File::Path, a core module from Perl to create or remove directory trees. An attacker can take advantage of this flaw to set the mode on an attacker-chosen file to an attacker-chosen value.

For Debian 7 'Wheezy', these problems have been fixed in version 5.14.2-21+deb7u5.

We recommend that you upgrade your perl 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 packages.
