Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Buffer overflow
EUVDB-ID: #VU14691
Risk: High
CVSSv4.0: 8.1 [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]
CVE-ID: CVE-2018-14618
CWE-ID:
CWE-120 - Buffer overflow
Exploit availability: No
DescriptionThe 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.

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
2) Use-after-free error
EUVDB-ID: #VU15672
Risk: Low
CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2018-16840
CWE-ID:
CWE-416 - Use After Free
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to use-after-free error in closing an easy handle in the 'Curl_close()' function. A remote unauthenticated attacker can specially crafted data, trigger memory corruption and cause the service to crash.

3) Heap-based buffer overflow
EUVDB-ID: #VU15673
Risk: Low
CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2018-16842
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to heap-based buffer over-read in the tool_msgs.c:voutf() function. A remote unauthenticated attacker can specially crafted data, trigger memory corruption to read back out-of-buffer data and cause the service to crash.
