CURL-CVE-2018-16890
No affected components available
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.
