Description

This security bulletin contains information about 1 vulnerability.


1) Out-of-bounds read (CVE-ID: CVE-2026-59198)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: 8.3 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to disclose sensitive information.

The vulnerability exists due to an out-of-bounds read in the TGA RLE encoder when saving a mode "1" image through the public save API with TGA RLE compression. A remote attacker can save a specially crafted image to disclose sensitive information.

The issue can serialize adjacent process heap bytes into the generated TGA file, and a maximum-width single-row image can expose nearly the full adjacent heap window.
