Description

Tim Wojtulewicz of Corelight reports:

Receiving DNS responses from async DNS requests (via

the lookup_addr, etc BIF methods) with the TTL set to

zero could cause the DNS manager to eventually stop being

able to make new requests.

Specially-crafted FTP packets with excessively long

usernames, passwords, or other fields could cause log

writes to use large amounts of disk space.

The find_all and find_all_ordered BIF methods could

take extremely large amounts of time to process incoming

data depending on the size of the input.
