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