CVE-2024-11403

Estado: AnalizadaMedia (6.9)—

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.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

El decodificador JPEG utilizado por el codificador JPEG XL al realizar la recompresión JPEG (es decir, si se utiliza JxlEncoderAddJPEGFrame en una entrada no confiable) no verifica correctamente los límites en presencia de códigos incompletos. Esto podría provocar una escritura fuera de los límites. En jpegli, que se publica como parte del mismo proyecto, está presente la misma vulnerabilidad. Sin embargo, el búfer relevante es parte de una estructura más grande y el código no hace suposiciones sobre los valores que se podrían sobrescribir. Sin embargo, el problema podría hacer que jpegli lea memoria no inicializada o direcciones de funciones."
