A buffer overflow exists in the Snort Back Orifice preprocessor that may allow a remote, unauthenticated attacker to execute arbitrary code, possibly with elevated privileges.
Snort is an open-source intrusion detection system (IDS). A lack of validation on attacker-controlled data may allow a buffer overflow to occur in the in Snort Back Orifice preprocessor. A remote, unauthenticated attacker may be able to trigger the buffer overflow by sending a specially crafted Back Orifice ping to a vulnerable Snort installation.
To exploit this vulnerability, an attacker does not need to send packets directly to the Snort sensor. It is sufficient to send packets to any of the hosts on the network monitored by Snort.
A remote attacker can execute arbitrary code with the privileges of the Snort process, typically root or SYSTEM.
This vulnerability was researched and reported by Internet Security Systems (ISS).
