Debian DLA-3593-1 : gerbv - LTS security update

critical Nessus Plugin ID 182404

Language:

Synopsis

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

Description

The remote Debian 10 host has a package installed that is affected by multiple vulnerabilities as referenced in the dla-3593 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 user able to control file input to Gerbv, between versions 2.4.0 and 2.10.0, can cause a crash and cause denial-of-service with a specially crafted Gerber RS-274X file. (CVE-2023-4508)

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 Debian 10 buster, these problems have been fixed in version 2.7.0-1+deb10u3.
