Description
This security bulletin contains information about 5 secuirty vulnerabilities.
1) NULL pointer dereference (CVE-ID: CVE-2021-20296)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error in the Dwa decompression functionality. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
2) Integer overflow (CVE-ID: CVE-2021-23215)
The vulnerability allows a remote attacker to perform a denial of service attack.
The vulnerability exists due to integer overflow in the DwaCompressor of OpenEXR. A remote attacker can pass specially crafted data to the application, trigger integer overflow and perform a denial of service (DoS) attack.
3) Integer overflow (CVE-ID: CVE-2021-26260)
The vulnerability allows a remote attacker to perform a denial of service attack.
The vulnerability exists due to integer overflow in the DwaCompressor of OpenEXR. A remote attacker can pass specially crafted data to the application, trigger integer overflow and perform a denial of service attack.
4) Heap-based buffer overflow (CVE-ID: CVE-2021-3598)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the readChars() function in ImfIO.h. A remote attacker can pass specially crafted data 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.
5) Heap-based buffer overflow (CVE-ID: CVE-2021-3605)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the rleUncompress function in ImfRle.cpp. A remote attacker can pass specially crafted data 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.
