CUPS incorrectly handles partially-negotiated SSL connections allowing for a Denial of Service.
CUPS provides a portable printing layer for UNIX-based operating systems.
CUPS does not properly handle partially-negotiated SSL connections. Upon receiving a partially-negotiated SSL connection, CUPS no longer accepts further incoming connections, as the initial connection never times out.
An attacker could partially negotiate an SSL connection with a CUPS server, and cause future connections to that server to fail, resulting in a Denial of Service.
There is no known workaround at this time.
All CUPS users should upgrade to the latest version:
