Debian DLA-3008-1 : openssl - LTS security update

critical Nessus Plugin ID 161207

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-3008 advisory.

The c_rehash script does not properly sanitise shell metacharacters to prevent command injection. This script is executed by update-ca-certificates, from ca-certificates, to re-hash certificates in /etc/ssl/certs/. An attacker able to place files in this directory could execute arbitrary commands with the privileges of the script. For Debian 9 stretch, this problem has been fixed in version 1.1.0l-1~deb9u6. We recommend that you upgrade your openssl packages. For the detailed security status of openssl please refer to its security tracker page at: https://security-tracker.debian.org/tracker/openssl 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 openssl packages.

For Debian 9 stretch, this problem has been fixed in version 1.1.0l-1~deb9u6.
