Vulnerability from cvelistv5

Severity ?
5.4 (Medium) - CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:L
CWE
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.
