CVE-2018-16890 (GCVE-0-2018-16890)

Vulnerability from cvelistv5 – Published: 2019-02-06 20:00 – Updated: 2026-04-15 20:53
VLAI
Summary
libcurl versions from 7.36.0 to before 7.64.0 is vulnerable to a heap buffer out-of-bounds read. The function handling incoming NTLM type-2 messages (`lib/vauth/ntlm.c:ntlm_decode_type2_target`) does not validate incoming data correctly and is subject to an integer overflow vulnerability. Using that overflow, a malicious or broken NTLM server could trick libcurl to accept a bad length + offset combination that would lead to a buffer read out-of-bounds.
