CVE-2018-4012 (GCVE-0-2018-4012)

Vulnerability from cvelistv5 – Published: 2019-01-03 23:00 – Updated: 2024-08-05 04:57

Summary

An exploitable buffer overflow vulnerability exists in the HTTP header-parsing function of the Webroot BrightCloud SDK. The function bc_http_read_header incorrectly handles overlong headers, leading to arbitrary code execution. An unauthenticated attacker could impersonate a remote BrightCloud server to trigger this vulnerability.
