Summary
The implementation of SYN cookies (syncookies) in FreeBSD 4.5 through 5.0-RELEASE-p3 uses only 32-bit internal keys when generating syncookies, which makes it easier for remote attackers to conduct brute force ISN guessing attacks and spoof legitimate traffic.
Exploit prediction (EPSS)
1.35% probability of exploitation in the next 30 days, higher than 72% of all scored CVEs.
