Debian DLA-2210-1 : apt security update

medium Nessus Plugin ID 136631

Language:

Synopsis

The remote Debian host is missing a security update.

Description

When normalizing ar member names by removing trailing whitespace and slashes, an out-out-bound read can be caused if the ar member name consists only of such characters, because the code did not stop at 0, but would wrap around and continue reading from the stack, without any limit.

For Debian 8 'Jessie', this problem has been fixed in version 1.0.9.8.6.

We recommend that you upgrade your apt 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.
