Description
This security bulletin contains information about 4 secuirty vulnerabilities.
1) Heap-based buffer overflow (CVE-ID: CVE-2020-27814)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in lib/openjp2/mqc.c. A remote attacker can pass specially crafted image to the application, 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.
2) Heap-based buffer overflow (CVE-ID: CVE-2020-27841)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error. A remote attacker can pass specially crafted image to the application, 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.
3) Out-of-bounds read (CVE-ID: CVE-2020-27843)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition. A remote attacker can create a specially crafted image, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system.
4) Heap-based buffer overflow (CVE-ID: CVE-2020-27845)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in lib/openjp2/pi.c. A remote attacker can pass specially crafted image, 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.
