critical Nessus Plugin ID 169342

Language:

Synopsis

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

Description

The remote Debian 11 host has a package installed that is affected by multiple vulnerabilities as referenced in the dsa-5306 advisory.

- An out-of-bounds write vulnerability exists in the RS-274X aperture macro variables handling functionality of Gerbv 2.7.0 and dev (commit b5f1eacd) and the forked version of Gerbv (commit 71493260). A specially- crafted gerber file can lead to code execution. An attacker can provide a malicious file to trigger this vulnerability. (CVE-2021-40393, CVE-2021-40394)

- A use-after-free vulnerability exists in the RS-274X aperture definition tokenization functionality of Gerbv 2.7.0 and dev (commit b5f1eacd) and Gerbv forked 2.7.1. A specially-crafted gerber file can lead to code execution. An attacker can provide a malicious file to trigger this vulnerability. (CVE-2021-40401)

- An information disclosure vulnerability exists in the pick-and-place rotation parsing functionality of Gerbv 2.7.0 and dev (commit b5f1eacd), and Gerbv forked 2.8.0. A specially-crafted pick-and-place file can exploit the missing initialization of a structure to leak memory contents. An attacker can provide a malicious file to trigger this vulnerability. (CVE-2021-40403)

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 gerbv packages.

For the stable distribution (bullseye), these problems have been fixed in version 2.7.0-2+deb11u2.
