CVE-2024-11498: Resource exhaustion via Stack overflow in libjxl

MediumCVSS 6.9 · v4.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 27/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 0.60% (FIRST EPSS).
Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. Special conditions such as timing or configuration are required.
Fixed version: libjxl (Alpine:v3.21) 0.10.4-r0; libjxl (Alpine:v3.23) 0.11.1-r0; jpeg-xl (Debian:12) 0.7.0-10+deb12u1.

Low priority for now. Upgrade to libjxl (Alpine:v3.21) 0.10.4-r0; libjxl (Alpine:v3.23) 0.11.1-r0; jpeg-xl (Debian:12) 0.7.0-10+deb12u1 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

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.
