Multiple format string vulnerabilities in lib/silcclient/command.c in Secure Internet Live Conferencing (SILC) Toolkit before 1.1.10, and SILC Client 1.1.8 and earlier, allow remote attackers to execute arbitrary code via format string specifiers in a channel name, related to (1) silc_client_command_topic, (2) silc_client_command_kick, (3) silc_client_command_leave, and (4) silc_client_command_users.
The product uses a function that accepts a format string as an argument, but the format string originates from an external source.
