CVE-2026-92454 · JPEG decoder: truncated segments are read past the image buffer, and a zero sampling factor hangs the decode
Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.
The GUIX software JPEG decoder reads four kinds of marker segment without checking that each is long enough to hold what it reads. A truncated segment is therefore read past the end of the caller's image buffer. Separately, a zero chroma sampling factor makes the block decode loop non-terminating. Both reproduce in the default configuration, in which `GX_SOFTWARE_DECODER_SUPPORT` is enabled.
