Summary
A flaw was found in GIMP. The PlayStation TIM loader, responsible for handling PlayStation image files, incorrectly calculates the size of the Color Look-Up Table (CLUT) due to an integer overflow.
This occurs when multiplying num_colors and num_cluts, both 16-bit unsigned short integers, resulting in a value exceeding the maximum integer limit. An attacker could exploit this by providing a specially crafted image file, leading to undefined behavior and causing the GIMP plug-in to abort, effectively resulting in a denial of service.
Conditions for Exploitation: Successful exploitation requires user interaction. An attacker must trick a user into manually opening a specially crafted, malicious PlayStation TIM image file within the GIMP application.
Impact Limitations: The vulnerability is strictly limited to a localized Denial of Service (DoS) where the specific file loader plug-in aborts. It does not allow for remote code execution, data exfiltration, or privilege escalation, and it does not compromise the broader system or network security.
Red Hat severity: Moderate — CVSS 5.5 (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H). Weakness: CWE-190.
Affected Red Hat products: Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9. Will not fix / out of support: Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7.
