CVE-2018-19115

CRITICAL

keepalived < 2.0.7 - Heap-Based Buffer Overflow via HTTP Status Code Parsing

Title source: llm
STIX 2.1

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.
