Ubuntu 20.04 LTS : libslirp vulnerability (USN-4437-1)

medium Nessus Plugin ID 139025

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

Ziming Zhang and VictorV discovered that libslirp incorrectly handled replying to certain ICMP echo requests. A remote attacker could possibly use this issue to cause libslirp to crash, resulting in a denial of service.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected libslirp-dev and / or libslirp0 packages.
