Severity: MODERATE
Description:
If Checkpoint Firewall-1 receives a number of spoofed UDP packets with Source IP = Destination IP, the firewall (and likely the machine hosting it) crashes.
NOTE:
This vulnerability while being posted to Bugtraq is currently being denied as a problem by the vendor. The following text was sent to SecurityFocus.
"Check Point takes this and all other possible security issues very seriously. In this case, we have made every effort to work with the authors and reproduce the reported behavior. However, even after extensive testing we have been unable to reproduce this vulnerability. This testing was done both with and without IP Spoofing protection enabled, with the provided source code and other tools. The authors could not provide us with valid FireWall-1 version information, although 3.0, 4.0, and 4.1 are listed as vulnerable; please note that version 3.0 is no longer supported on non-embedded platforms.
At this time, Check Point does not believe this is an actual vulnerability. If anyone has successfully reproduced this condition or has further information, please contact SECURITY-ALERT@checkpoint.com."
Affected Products:
- Check Point Software Firewall-1 3.0.0
