Algorithmic complexity vulnerability in the ssl.matchhostname function in Python 3.2.x, 3.3.x, and earlier, and unspecified versions of python-backports-sslmatch_hostname as used for older Python versions, allows remote attackers to cause a denial of service (CPU consumption) via multiple wildcard characters in the common name in a certificate.
