Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) Buffer overflow (CVE-ID: CVE-2020-19131)
The vulnerability allows a remote attacker to perform a denial of service attack.
The vulnerability exists due to a boundary error in the invertImage() function in the tiffcrop component. A remote attacker can pass a specially crafted file to the application and perform a denial of service attack.
2) Buffer overflow (CVE-ID: CVE-2020-19144)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing files within the _TIFFmemcpy() funtion in "tif_unix.c". A remote attacker can create a specially crafted image file, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
3) NULL pointer dereference (CVE-ID: CVE-2022-0907)
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 tiffcrop in libtiff. A remote attacker can trigger denial of service conditions via a crafted tiff file.
4) NULL pointer dereference (CVE-ID: CVE-2022-0908)
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 memcpy() function within TIFFFetchNormalTag () in tif_dirread.c. A remote attacker can pass specially crafted TIFF file to the application and perform a denial of service (DoS) attack.
5) Division by zero (CVE-ID: CVE-2022-0909)
The vulnerability allows a remote attacker to perform a denial of service attack.
The vulnerability exists due to a division by zero error in the tiffcrop component. A remote attacker can pass a specially crafted TIFF file to the application and crash it.
6) Out-of-bounds read (CVE-ID: CVE-2022-0924)
The vulnerability allows a remote attacker to perform a denial-of-service attack.
The vulnerability exists due to a boundary condition. A remote attacker can create a specially crafted TIFF file, trick the victim into opening it, trigger out-of-bounds read error and perform a denial-of-service attack.
7) Out-of-bounds read (CVE-ID: CVE-2022-22844)
The vulnerability allows a remote attacker to perform a denial of service attack.
The vulnerability exists due to a boundary condition in the _TIFFmemcpy() function in tif_unix.c in certain situations involving a custom tag and 0x0200 as the second word of the DE field. A remote attacker can pass a specially crafted file and perform a denial of service attack.
