EUVDB-ID: #VU86755

Risk: High

CVSSv4.0: 8.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2023-52356

CWE-ID: CWE-787 - Out-of-bounds write

Exploit availability: No

Description

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when processing untrusted input within the TIFFReadRGBATileExt() API. A remote attacker can pass a specially crafted TIFF file to the application, trigger an out-of-bounds write and execute arbitrary code on the target system.

Mitigation

Update the affected package tiff to the latest version.
