CVE-2024-11498: Libjxl Project Libjxl

High severity, CVSS 7.5. EPSS: 0.6% chance of exploitation in the next 30 days.

There exists a stack buffer overflow in libjxl. A specifically-crafted file can cause the JPEG XL decoder to use large amounts of stack space (up to 256mb is possible, maybe 512mb), potentially exhausting the stack. An attacker can craft a file that will cause excessive memory usage. We recommend upgrading past commit 65fbec56bc578b6b6ee02a527be70787bbd053b0.

Affected products

• Libjxl Project Libjxl: before 0.8.4 (fixed in 0.8.4)
