libjxl: Uncontrolled Resource Consumption
CVE-2024-11498 is a high-severity uncontrolled resource consumption vulnerability in libjxl, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 65fbec56bc578b6b6ee02a527be70787bbd053b0 as the first without the flaw, so updating libjxl to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.6% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update libjxl to 65fbec56bc578b6b6ee02a527be70787bbd053b0 or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

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.

The underlying weakness: Uncontrolled Resource Consumption
The product does not properly control the allocation and maintenance of a limited resource.
How developers prevent this class of flaw
- Ensure that protocols have specific limits of scale placed on them.
- Ensure that all failures in resource allocation place the system into a safe posture.
