three security issues during a security audit. A heap overflow allowed
the execution of arbitrary code (CVE-2011-0427 ), a denial of service
vulnerability was found in the zlib compression handling and some key
memory was incorrectly zeroed out before being freed. The latter two
issues do not yet have CVE identifiers assigned. The Debian Security
