Description

This security bulletin contains information about 3 vulnerabilities.


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.


2) Use-after-free error (CVE-ID: CVE-2018-16840)

CWE-ID: CWE-416 - Use After Free

CVSSv4: 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


The 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 (CVE-ID: CVE-2018-16842)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

CVSSv4: 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


The 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.
