critical Nessus Plugin ID 144735

Language:

Synopsis

The remote Debian host is missing a security update.

Description

It was discovered that there was an issue in the gssproxy privilege separation caused by gssproxy not unlocking cond_mutex prior to calling pthread_exit.

For Debian 9 'Stretch', this problem has been fixed in version 0.5.1-2+deb9u1.

We recommend that you upgrade your gssproxy packages.

For the detailed security status of gssproxy please refer to its security tracker page at:

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 gssproxy package.
