Bug #5168
Updated by Victor Julien about 2 years ago
A rule like @alert ip any any -> 0.0.0.5/0.0.0.5 any (sid:1;)@ fails to work properly, hits a @DEBUG_VALIDATE_BUG_ON@ and leaks memory. The engine internally only correctly handles netmasks that can be expressed through the CIDR notation as well. !cidr-table.png! !Screenshot from 2022-03-03 08-28-05.png!
