keepalived before 2.0.7 has a heap-based buffer overflow when parsing HTTP status codes resulting in DoS or possibly unspecified other impact, because extract_status_code in lib/html.c has no validation of the status code and instead writes an unlimited amount of data to the heap.

Affected: Ubuntu:16.04:LTS: keepalived, Ubuntu:18.04:LTS: keepalived

It was discovered that Keepalived incorrectly handled certain HTTP status response codes. A remote attacker could use this issue to cause Keepalived to crash, resulting in a denial of service, or possibly execute arbitrary code.
