Description

This security bulletin contains information about 4 secuirty vulnerabilities.

1) Stack-based buffer overflow (CVE-ID: CVE-2022-23803)

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

The vulnerability exists due to a boundary error in the Gerber Viewer gerber and excellon coordinates parsing functionality within "ReadXYCoord". A remote unauthenticated attacker can use a specially crafted gerber or excellon file, trigger stack-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

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

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.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

3) Stack-based buffer overflow (CVE-ID: CVE-2022-23947)

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

The vulnerability exists due to a boundary error in "DCodeNumber" 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.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

4) Stack-based buffer overflow (CVE-ID: CVE-2022-23804)

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

The vulnerability exists due to a boundary error in the Gerber Viewer gerber and excellon coordinates parsing functionality within "ReadIJCoord". A remote unauthenticated attacker can use a specially crafted gerber or excellon file, trigger stack-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
