GLSA-200703-12 : SILC Server: Denial of Service
Low Nessus Plugin ID 24829
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200703-12 (SILC Server: Denial of Service)
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.
SolutionAll SILC Server users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-im/silc-server-1.0.2-r1'
