- Summary
- NTLM type-2 out-of-bounds buffer read
- Details
-
libcurl contains a heap buffer out-of-bounds read flaw.
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.
