Description
This security bulletin contains information about 5 secuirty vulnerabilities.
1) Buffer overflow (CVE-ID: CVE-2020-35522)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing TIFF images in tif_pixarlog.c. A remote attacker can create a specially crafted TIFF image, 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.
2) NULL pointer dereference (CVE-ID: CVE-2022-0561)
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 TIFFFetchStripThing() in tif_dirread.c. A remote attacker can trick victim to open specially crafted TIFF file and perform a denial of service (DoS) attack.
3) NULL pointer dereference (CVE-ID: CVE-2022-0562)
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 TIFFReadDirectory() in tif_dirread.c. A remote attacker can trick victim to open specially crafted TIFF file and perform a denial of service (DoS) attack.
4) Out-of-bounds write (CVE-ID: CVE-2022-0891)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing TIFF file in ExtractImageSection() function in tiffcrop.c. A remote attacker can create a specially crafted TIFF file, trick the victim into opening it using the affected software, trigger out-of-bounds write and execute arbitrary code on the target system.
5) Reachable Assertion (CVE-ID: CVE-2022-0865)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a reachable assertion in the tiffcp component. A remote attacker can trick a victim to open a specially crafted TIFF file and perform a denial of service attack.
