From ${URL} : The dumbdbm module uses an unchecked call to eval() in the _update method, which is called in response to a call to dumbdbm.open(), and is used to load the index from the directory file. This poses a security vulnerability because it allows an attacker to execute arbitrary code on the victim's machine by inserting python code into the DBM directory file. This vulnerability could allow an attacker to execute arbitrary commands on the victim machine, potentially allowing them to deploy malware, gain system access, destroy files and data, expose sensitive information, etc. @maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.
Is this bug being addressed by Bug #532232?
