1) Division by zero (CVE-ID: CVE-2022-2056)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a division by zero error when parsing TIFF files in tiffcrop. A remote attacker can trick the victim to open a specially crafted file and crash the affected application.


2) Division by zero (CVE-ID: CVE-2022-2057)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a division by zero error when parsing TIFF files in tiffcrop. A remote attacker can trick the victim to open a specially crafted file and crash the affected application.

3) Division by zero (CVE-ID: CVE-2022-2058)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a division by zero error when parsing TIFF files in tiffcrop. A remote attacker can trick the victim to open a specially crafted file and crash the affected application.


4) Stack-based buffer overflow (CVE-ID: CVE-2022-34526)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error within the _TIFFVGetField() function in Tiffsplit. A remote attacker can pass specially crafted file to the application, trigger a stack-based buffer overflow and perform a denial of service (DoS) attack.


5) Integer overflow (CVE-ID: CVE-2022-3970)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to integer overflow within the TIFFReadRGBATileExt() function in libtiff/tif_getimage.c. A remote attacker can trick the victim to open a specially crafted TIFF file, trigger an integer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
