Description filip ambroz 2022-01-25 10:04:08 UTC
Couple of invalid memory read accesses have been found, that could possibly lead to remote DoS, remote information leaks or otherwise undefined behaviour. Furthermore, a way to trigger a 100 % CPU loop has been found.

1) Possibly invalid memory reference in `strnlen()` call in `forward_dns_reply()` (CVE-2022-23097)
2) TCP Receive Path does not Check for Presence of Sufficient Header Data (CVE-2022-23096)
3) TCP Receive Path Triggers 100 % CPU loop if DNS server does not Send Back Data (CVE-2022-23098)
4) TCP DNS Operation is Broken due to Bad TCP Length Header
