FKIE_CVE-2024-11403

Vulnerability from fkie_nvd - Published: 2024-11-25 14:15 - Updated: 2025-07-24 13:25
Severity ?
9.8 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Summary
There exists an out of bounds read/write in LibJXL versions prior to commit 9cc451b91b74ba470fd72bd48c121e9f33d24c99. The JPEG decoder used by the JPEG XL encoder when doing JPEG recompression (i.e. if using JxlEncoderAddJPEGFrame on untrusted input) does not properly check bounds in the presence of incomplete codes. This could lead to an out-of-bounds write. In jpegli which is released as part of the same project, the same vulnerability is present. However, the relevant buffer is part of a bigger structure, and the code makes no assumptions on the values that could be overwritten. The issue could however cause jpegli to read uninitialised memory, or addresses of functions.

El decodificador JPEG utilizado por el codificador JPEG XL al realizar la recompresi\u00f3n JPEG (es decir, si se utiliza JxlEncoderAddJPEGFrame en una entrada no confiable) no verifica correctamente los l\u00edmites en presencia de c\u00f3digos incompletos. Esto podr\u00eda provocar una escritura fuera de los l\u00edmites. En jpegli, que se publica como parte del mismo proyecto, est\u00e1 presente la misma vulnerabilidad. Sin embargo, el b\u00fafer relevante es parte de una estructura m\u00e1s grande y el c\u00f3digo no hace suposiciones sobre los valores que se podr\u00edan sobrescribir. Sin embargo, el problema podr\u00eda hacer que jpegli lea memoria no inicializada o direcciones de funciones."
