Synopsis
=3D=3D=3D=3D=3D=3D=3D=3D
SILC Server is affected by a Denial of Service vulnerability.
Background
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
SILC Server is a server for the Secure Internet Live Conferencing
(SILC) protocol.
Affected packages
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-im/silc-server < 1.0.2-r1 >=3D 1.0.2-r1
Description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
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
=3D=3D=3D=3D=3D=3D
A remote attacker could cause the server to crash, resulting in a
Denial of Service.
Workaround
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
There is no known workaround at this time.
Resolution
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
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
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
