Name of the Vulnerable Software and Affected Versions Apport versions prior to 2.20.4

Description An issue in Apport allows remote attackers to execute arbitrary Python code. This occurs when Apport reads the CrashDB field in apport/ui.py and evaluates it as Python code if the field begins with a "{".

Recommendations For versions prior to 2.20.4, update to version 2.20.4 or later to resolve the issue. As a temporary workaround, consider restricting access to the CrashDB field to minimize the risk of exploitation.
