Synopsis ========
SILC Server is affected by a Denial of Service vulnerability.
Background ==========
SILC Server is a server for the Secure Internet Live Conferencing (SILC) protocol.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-im/silc-server < 1.0.2-r1 >=3D 1.0.2-r1
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 ">=3Dnet-im/silc-server-1.0.2-r1"
Availability ============
This GLSA and any updates to it are available for viewing at the Gentoo Security Website:
