Thanks for taking the time to report this bug and helping to make Ubuntu better. Since the package referred to in this bug is in universe or multiverse, it is community maintained. If you are able, I suggest coordinating with upstream and posting a debdiff for this issue. When a debdiff is available, members of the security team will review it and publish the package. See the following link for more information: https://wiki.ubuntu.com/SecurityTeam/UpdateProcedures

Hello Michał, thanks for the bug report.

Canonical is a CNA that can assign CVEs, but we are limited in which programs and which conditions we can assign numbers. For this issue, please request a CVE from https://cveform.mitre.org/ .

Typically, command line parameters are assumed to be trusted inputs; there's a chance that this issue may not be seen as a security issue, but rather a standard bug.

Thanks
