medium Nessus Plugin ID 154936

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

The remote Debian 9 host has packages installed that are affected by a vulnerability as referenced in the dla-2809 advisory.

 Stefan Walter found that udisks2, a service to access and manipulate storage devices, could cause denial of service via system crash if a corrupted or specially crafted ext2/3/4 device or image was mounted, which could happen automatically on certain environments. For Debian 9 stretch, this problem has been fixed in version 2.1.8-1+deb9u1. We recommend that you upgrade your udisks2 packages. For the detailed security status of udisks2 please refer to its security tracker page at: https://security- tracker.debian.org/tracker/udisks2 Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: https://wiki.debian.org/LTS

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the udisks2 packages.

For Debian 9 stretch, this problem has been fixed in version 2.1.8-1+deb9u1.
