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.

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.

    Claudio Bozzato discovered that Gerbv incorrectly handled certain Gerber files. An attacker could possibly     use this issue to crash Gerbv (resulting in a denial of service), or execute arbitrary code. This issue     only affected Ubuntu 14.04 LTS, Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, and Ubuntu 20.04 LTS. (CVE-2021-40391,     CVE-2021-40394)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

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)
