Pro-face Pro-Server EX up to 1.23.000 C Runtime ProServr.exe memory corruption

CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability was found in Pro-face Pro-Server EX up to 1.23.000. It has been rated as very critical. This issue affects some unknown functionality of the file ProServr.exe of the component C Runtime. The manipulation with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Pro-face WinGP PC Runtime 3.1.00 and earlier, and ProServr.exe in Pro-face Pro-Server EX 1.30.000 and earlier, does not properly check packet sizes before reusing packet memory buffers, which allows remote attackers to cause a denial of service (heap memory corruption) or possibly have unspecified other impact via a short crafted packet with a certain opcode.
