Debian DLA-1429-1 : sssd security update

high Nessus Plugin ID 111111

Language:

Synopsis

The remote Debian host is missing a security update.

Description

The UNIX pipe which sudo uses to contact SSSD and read the available sudo rules from SSSD has too wide permissions, which means that anyone who can send a message using the same raw protocol that sudo and SSSD use can read the sudo rules available for any user.

For Debian 8 'Jessie', these problems have been fixed in version 1.11.7-3+deb8u1.

We recommend that you upgrade your sssd 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.
