What is CVE-2024-11498?
CVE-2024-11498 is a medium-severity denial of service vulnerability in libjxl, published on 25 Nov 2024. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.
Official description
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.
