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.
The product uses a function that accepts a format string as an argument, but the format string originates from an external source.
