1) Buffer overflow (CVE-ID: CVE-2018-14618)

CWE-ID: CWE-120 - Buffer overflow

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists on systems with a 32-bit size_t and that use more than 2 GB of memory for the password field due to a buffer overflow in Curl_ntlm_core_mk_nt_hash() in 'lib/curl_ntlm_core.c' when handling malicious input. A remote unauthenticated attacker can send a specially crafted NTLM authentication password, trigger memory corruption and execute arbitrary code with elevated privileges.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
