Debian DLA-2094-1 : sudo security update

high Nessus Plugin ID 133414

Synopsis

The remote Debian host is missing a security update.

Description

A stack-based buffer overflow vulnerability in sudo, a program designed to provide limited super user privileges to specific users, triggerable when configured with the pwfeedback option enabled. An unprivileged user can take advantage of this flaw to obtain full root privileges.

For Debian 8 'Jessie', this problem has been fixed in version 1.8.10p3-1+deb8u7.

We recommend that you upgrade your sudo 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 sudo, and sudo-ldap packages.
