NVD Description

Note: Versions mentioned in the description apply only to the upstream keepalived package and not the keepalived package as distributed by Oracle. See How to fix? for Oracle:7 relevant fixed versions and status.

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.
