Ubuntu 14.04 LTS / 15.04 : simplestreams vulnerability (USN-2746-1)

Medium Nessus Plugin ID 86147


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


It was discovered that Simple Streams did not properly perform gpg verification in some situations. A remote attacker could use this to perform a man-in-the-middle attack and inject malicious content into the stream.

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 packages.
