Description
This security bulletin contains information about 3 secuirty vulnerabilities.
1) Buffer overflow (CVE-ID: CVE-2018-14618)
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)
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)
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.
