Title: ISS RealSecure 3.2.x Fragmented SYN Packets DoS Vulnerability
Severity: MODERATE
Description:
ISS RealSecure 3.2.x can be disabled remotely via fragmented packets with the SYN flag set.
On NT, after crashing the service will restart, and generates an Application Log event. If the packets are continuosly resent, detection is effectively halted while the service repeatedly restarts.
On Solaris, the process crashes, all detection stops, and a report is generated to the console. Also, on Solaris it is possible to crash the process with a flood of unfragmented packets if certain flgas (in addition to SYN) are set.
Affected Products:
- Internet Security Systems RealSecure 3.2.0
