Medium Nessus Plugin ID 70269
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionFlorian Weimer discovered that Python incorrectly handled matching multiple wildcards in ssl certificate hostnames. An attacker could exploit this to cause Python to consume resources, resulting in a denial of service. (CVE-2013-2099)
Ryan Sleevi discovered that Python did not properly handle certificates with NULL characters in the Subject Alternative Name field. An attacker could exploit this to perform a man in the middle attack to view sensitive information or alter encrypted communications. (CVE-2013-4238).
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.
SolutionUpdate the affected python3.3 and / or python3.3-minimal packages.
