CWEhttps://cwe.mitre.org/data/definitions/134.html

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.

Weakness

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