Synopsis

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

Description

The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 LTS / 22.04 ESM host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6209-1 advisory.

 - An out-of-bounds write vulnerability exists in the drill format T-code tool number functionality of Gerbv 2.7.0, dev (commit b5f1eacd), and the forked version of Gerbv (commit 71493260). A specially-crafted drill file can lead to code execution. An attacker can provide a malicious file to trigger this vulnerability.
 (CVE-2021-40391)

 - 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)

 - An out-of-bounds read vulnerability exists in the RS-274X aperture macro outline primitive functionality of Gerbv 2.7.0 and dev (commit b5f1eacd) and the forked version of Gerbv (commit d7f42a9a). A specially- crafted Gerber file can lead to information disclosure. An attacker can provide a malicious file to trigger this vulnerability. (CVE-2021-40400)

 - 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.
