medium Nessus Plugin ID 151679

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5009-1 advisory.

 Qiuhao Li discovered that libslirp incorrectly handled certain header data lengths. An attacker inside a guest could possibly use this issue to leak sensitive information from the host. This issue only affected Ubuntu 20.04 LTS and Ubuntu 20.10. (CVE-2020-29129, CVE-2020-29130)

 It was discovered that libslirp incorrectly handled certain udp packets. An attacker inside a guest could possibly use this issue to leak sensitive information from the host. (CVE-2021-3592, CVE-2021-3593, CVE-2021-3594, CVE-2021-3595)

Tenable has extracted the preceding description block directly from the Ubuntu 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

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