Snort is reported prone to a remote denial of service vulnerability. The vulnerability is reported to exist in the DecodeTCPOptions() function of 'decode.c', and is as a result of a failure to sufficiently handle malicious TCP packets.
|
|
|
|
A remote attacker may trigger this vulnerability to crash a remote Snort server and in doing so may prevent subsequent malicious attacks from being detected.
