SILC Server is affected by a Denial of Service vulnerability.
|Package||net-im/silc-server on all architectures|
|Affected versions||< 1.0.2-r1|
|Unaffected versions||>= 1.0.2-r1|
SILC Server is a server for the Secure Internet Live Conferencing (SILC) protocol.
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.
A remote attacker could cause the server to crash, resulting in a Denial of Service.
There is no known workaround at this time.
All SILC Server users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-im/silc-server-1.0.2-r1"
