Ubuntu 5.04 : libksba vulnerability (USN-365-1)

Medium Nessus Plugin ID 27945


The remote Ubuntu host is missing one or more security-related patches.


A parsing failure was discovered in the handling of X.509 certificates that contained extra trailing data. Malformed or malicious certificates could cause services using libksba to crash, potentially creating a denial of service.

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 libksba-dev and / or libksba8 packages.
