SILC Toolkit silc_fingerprint() buffer overflow
| silctoolkit-silcfingerprint-bo (41012) |  High Risk |
Description:
SILC Toolkit is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the silc_fingerprint() function. By sending a specially-crafted request containing overly long data, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
