Debian DSA-5354-1 : snort - security update

high Nessus Plugin ID 171628

Language:

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5354 advisory.

Multiple security vulnerabilities were discovered in snort, a flexible Network Intrusion Detection System, which could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition or bypass filtering technology on an affected device and ex-filtrate data from a compromised host. For the stable distribution (bullseye), these problems have been fixed in version 2.9.20-0+deb11u1. We recommend that you upgrade your snort packages. For the detailed security status of snort please refer to its security tracker page at: https://security-tracker.debian.org/tracker/snort

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

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

Solution

Upgrade the snort packages.

For the stable distribution (bullseye), these problems have been fixed in version 2.9.20-0+deb11u1.
