Ubuntu 12.04 LTS / 12.10 / 13.04 : libmodule-signature-perl vulnerability (USN-1896-1)

Medium Nessus Plugin ID 67187


The remote Ubuntu host is missing a security-related patch.


Florian Weimer discovered that the Module::Signature perl module incorrectly loaded unknown ciphers from relative directories. An attacker could possibly use this flaw to execute arbitrary code when a signature is verified.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected libmodule-signature-perl package.
