The vulnerability exists due to a boundary error when processing untrusted input in mod_sed. A remote attacker can trigger out-of-bounds write and execute arbitrary code on the target system.


2) Infinite loop (CVE-ID: CVE-2022-0778)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
