Description
This security bulletin contains information about 4 secuirty vulnerabilities.
1) Input validation error (CVE-ID: CVE-2019-16675)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can send a specially crafted PC Worx or Config+ project file and execute arbitrary code on the target system.
2) Use-after-free (CVE-ID: CVE-2019-12871)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error when parsing the BCP files. A remote attacker can exchange the original PC Worx or Config+ project file with the manipulated one on the application programming workstation and execute arbitrary code on the target system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
3) Access of Uninitialized Pointer (CVE-ID: CVE-2019-12870)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.The vulnerability exists due to access of uninitialized pointer when parsing the BCP files. A remote attacker can exchange the original PC Worx or Config+ project file with the manipulated one on the application programming workstation and execute arbitrary code on the target system.
4) Out-of-bounds read (CVE-ID: CVE-2019-12869)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition when parsing the BCP files. A remote attacker can exchange the original PC Worx or Config+ project file with the manipulated one on the application programming workstation, trigger out-of-bounds read error and read contents of memory on the system.
