This security bulletin contains information about 2 vulnerabilities.


1) Stack-based buffer overflow (CVE-ID: CVE-2022-23946)

CWE-ID: CWE-121 - Stack-based buffer overflow

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in "GCodeNumber" in the Gerber Viewer gerber and excellon GCode/Dcode parsing functionality. A remote unauthenticated attacker can #CONDITION2#, trigger stack-based buffer overflow and execute arbitrary code on the target system.
