Description

This security bulletin contains information about 2 vulnerabilities.

1) NULL pointer dereference (CVE-ID: CVE-2025-8534)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green

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

The vulnerability exists due to NULL pointer dereference within the PS_Lvl2page() function in tools/tiff2ps.c. A remote attacker can pass a specially crafted image to the application and perform a denial of service (DoS) attack.

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

The vulnerability exists due to a boundary error within the readSeparateStripsetoBuffer() function in tools/tiffcrop.c. A remote attacker can pass a specially crafted image file to the tiffcrop binary, trigger a stack-based buffer overflow and execute arbitrary code on the target system.
