|Gentoo Linux Security Advisory
Title: SILC Server: Denial of Service (GLSA 200703-12)
Date: March 14, 2007
SILC Server is affected by a Denial of Service vulnerability.
SILC Server is a server for the Secure Internet Live Conferencing (SILC) protocol.
Vulnerable: < 1.0.2-r1
Unaffected: >= 1.0.2-r1
Architectures: All supported architectures
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"
