QID 375471: Curl Heap Buffer Out-of-Bounds Read Vulnerability

cURL is a computer software project providing a library and command-line tool for transferring data using various protocols.

libcurl contains a heap buffer out-of-bounds read flaw. The function handling incoming NTLM type-2 messages does not validate incoming data correctly and is subject to an integer overflow vulnerability.

Affected Versions:
curl version 7.36.0 to 7.63.0

QID Detection Logic (Authenticated):
It invokes curl --version command to check the vulnerable version of cURL

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.

CVSS V3 rated as High - 7.5 severity.

CVSS V2 rated as Medium - 5 severity.
