Description:
Some vulnerabilities have been reported in SILC Toolkit and SILC Server, which can be exploited by malicious people to cause a DoS (Denial of Service) and potentially compromise a vulnerable system.
1) An incorrect format specifier within the "silc_asn1_encoder()" function in lib/silcasn1/silcasn1_encode.c can be exploited to cause a memory corruption.
Successful exploitation requires a 64bit system.
2) An incorrect format specifier within the "silc_http_server_parse()" function in lib/silchttp/silchttpserver.c can be exploited to cause a memory corruption by sending specially crafted requests to a vulnerable HTTP server.
Successful exploitation requires a 64bit system and that e.g. the internal HTTP server for statistics is enabled.
