Name of the Vulnerable Software and Affected Versions devscripts versions through 2.18.3

Description The issue allows code execution through unsafe YAML loading because YAML::Syck is used without a configuration that prevents unintended blessing. This is related to the scripts/grep-excuses.pl in Debian devscripts.

Recommendations For devscripts versions through 2.18.3, consider updating the YAML::Syck configuration to prevent unintended blessing as a temporary workaround until a patch is available.
