    Medium [CVE-2026-59198] Information disclosure via TGA RLE encoder out-of-bounds read

    CVE-2026-59198Source published Source updated

    Pillow is a Python imaging library. From 5.2.0 until 12.3.0, Pillow's TGA RLE encoder reads past its packed row buffer when saving a mode 1 image with TGA RLE compression, allowing adjacent process heap bytes to be copied into the generated TGA file. This issue is fixed in version 12.3.0. This out-of-bounds read allows adjacent process heap memory to be copied into the generated TGA file, potentially leading to information disclosure. Exploitation requires the application to save attacker-influenced images in TGA format with RLE compression, which is an uncommon operation in affected Red Hat products. Red Hat severity: Moderate — CVSS 6.5 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:L). Weakness: CWE-125. Affected Red Hat products: Lightspeed Core; OpenShift Lightspeed; Red Hat AI…
