Description
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.

• keepalived keepalived (< 2.0.7)
• debian debian linux 8.0
• redhat enterprise linux server 7.0
• redhat enterprise linux server aus 7.6
• redhat enterprise linux server eus 7.6
