licq: DoS via large number of connections

licq before 1.3.6 allows remote attackers to cause a denial of service (file-descriptor exhaustion and application crash) via a large number of connections.

security flaw

licq before 1.0.3 allows remote attackers to execute arbitrary commands via shell metacharacters in a URL.

security flaw

Buffer overflow in logging functions of licq before 1.0.3 allows remote attackers to cause a denial of service, and possibly execute arbitrary commands.

Buffer overflow in licq 1.0.4 and earlier allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long string of format string characters such as "%d".

Format string vulnerability in LICQ 1.2.6, 1.0.3 and possibly other versions allows remote attackers to perform unknown actions via format string specifiers.
