CVE-2011-3150
Software Center in Ubuntu 11.10, 11.04 10.10 does not properly validate server certificates, which allows remote attackers to execute arbitrary code or obtain sensitive information via a man-in-the-middle (MITM) attack.
Does this matter?
Lower severity and a low EPSS score (1.90%). Track it; it rarely justifies an emergency change on its own.
