Package : silc-toolkit
Date : September 15, 2009
Affected: 2008.1, 2009.0
_______________________________________________________________________

Problem Description:

Multiple vulnerabilities was discovered and corrected in silc-toolkit:

Multiple format string vulnerabilities in lib/silcclient/client_entry.c
in Secure Internet Live Conferencing (SILC) Toolkit before 1.1.10, and
SILC Client before 1.1.8, allow remote attackers to execute arbitrary
code via format string specifiers in a nickname field, related to the
(1) silc_client_add_client, (2) silc_client_update_client, and (3)
silc_client_nickname_format functions (CVE-2009-3051).

The silc_asn1_encoder function in lib/silcasn1/silcasn1_encode.c in
Secure Internet Live Conferencing (SILC) Toolkit before 1.1.8 allows
remote attackers to overwrite a stack location and possibly execute
arbitrary code via a crafted OID value, related to incorrect use of
a %lu format string (CVE-2008-7159).

The silc_http_server_parse function in lib/silchttp/silchttpserver.c in
the internal HTTP server in silcd in Secure Internet Live Conferencing
(SILC) Toolkit before 1.1.9 allows remote attackers to overwrite
a stack location and possibly execute arbitrary code via a crafted
Content-Length header, related to incorrect use of a %lu format string
(CVE-2008-7160).

Multiple format string vulnerabilities in lib/silcclient/command.c
in Secure Internet Live Conferencing (SILC) Toolkit before 1.1.10,
and SILC Client 1.1.8 and earlier, allow remote attackers to execute
arbitrary code via format string specifiers in a channel name, related
to (1) silc_client_command_topic, (2) silc_client_command_kick,
(3) silc_client_command_leave, and (4) silc_client_command_users
(CVE-2009-3163).

This update provides a solution to these vulnerabilities.
