Description
This security bulletin contains information about 5 secuirty vulnerabilities.
1) Stack-based buffer overflow (CVE-ID: CVE-2021-22637)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing VPR files. A remote unauthenticated attacker can trigger stack-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
2) Out-of-bounds read (CVE-ID: CVE-2021-22655)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition when processing project files. A remote attacker can trigger out-of-bounds read error and read contents of memory on the system.
3) Out-of-bounds write (CVE-ID: CVE-2021-22653)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted input when processing project files. A remote attacker can trigger out-of-bounds write and execute arbitrary code on the target system.
4) Access of Uninitialized Pointer (CVE-ID: CVE-2021-22639)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to an uninitialized pointer issue when processing VPR files. A remote attacker can use a specially crafted project file and execute arbitrary code on the target system.
5) Heap-based buffer overflow (CVE-ID: CVE-2021-22641)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing VPR files. A remote attacker can trigger heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
