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.

CVE-2018-16890 [HIGH] curl vulnerabilities
Title: curl vulnerabilities
Summary: Several security issues were fixed in curl.
Wenxiang Qian discovered that curl incorrectly handled certain NTLM
authentication messages. A remote attacker could possibly use this issue to
cause curl to crash, resulting in a denial of service. This issue only
applied to Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, and Ubuntu 18.10.

CVE-2018-16890 [HIGH] CWE-190 curl: NTLM type-2 heap out-of-bounds buffer read
curl: NTLM type-2 heap out-of-bounds buffer read
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.
An out-of-bounds read flaw was found in the way curl handled NTLMv2 type-2 headers. When connecting to a remote malicious server which uses NTLM authentication, the flaw could cause curl to crash.
