HIGHCVSS 7.5/10EPSS 0.61%

Last modified

CVE-2024-11498 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. 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. EPSS estimates a 0.61% chance of exploitation in the next 30 days.
