 _______________________________________________________________________

 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.
