Details

enabled. A remote attacker could use this issue to cause the server to
crash, resulting in a denial of service. This issue only affected Ubuntu
12.04 LTS. (CVE-2014-0032)

certificates containing wildcards. A remote attacker could exploit this to
perform a man in the middle attack to view sensitive information or alter
encrypted communications. (CVE-2014-3522)

credentials. A malicious server could possibly use this issue to obtain
credentials cached for a different server. (CVE-2014-3528)
