Description
This security bulletin contains information about 2 vulnerabilities.
1) Stack-based buffer overflow (CVE-ID: CVE-2017-14016)
CWE-ID: CWE-121 - Stack-based buffer overflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:A/U:Amber
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to improper validation of the length of user-supplied data. A remote attacker can trick the victim into loading a specially crafted input, trigger stack-based buffer overflow and execute arbitrary code with privileges of the current user.
Successful exploitation of the vulnerability may result in system compromise.
2) Untrusted pointer dereference (CVE-ID: CVE-2017-12719)
CWE-ID: CWE-822 - Untrusted Pointer Dereference
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 possibly execute arbitrary code on the target system.
The weakness exists due to untrusted pointer dereference. A remote attacker can supply a specially crafted program, cause the application to become unavailable and possibly execute arbitrary code with elevated privileges.
Successful exploitation of the vulnerability may result in system compromise.
