Description

Background

SILC Server is a server for the Secure Internet Live Conferencing (SILC) protocol.

Description

Frank Benkstein discovered a possible NULL pointer dereference in apps/silcd/command.c if a new channel is created without specifying a valid hmac or cipher algorithm name.

Impact

A remote attacker could cause the server to crash, resulting in a Denial of Service.

Workaround

There is no known workaround at this time.

Resolution

All SILC Server users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=net-im/silc-server-1.0.2-r1"
