Description:
Frank Benkstein has reported a vulnerability in SILC Server, which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to a NULL-pointer dereference error within apps/silcd/command.c. This can be exploited to crash the service by connecting to the server, joining or creating a channel, and then specifying invalid hmac or cipher values.
The vulnerability is reported in version 1.02. Prior versions may also be affected.
