CVE-2013-6629: Infoleak

First published: Tue Nov 12 2013(Updated: )

It was reported [1],[2] that libjpeg and libjpeg-turbo would use uninitialized memory when decoding images with missing SOS data for the luminance component (Y) in the presence of valid chroma data (Cr, Cb). An example proof of concept that can be viewed in a browser is also available [3]. This was reported and fixed initially in Google Chrome/Chromium; it does not appear to be fixed in upstream libjpeg or libjpeg-turbo yet. Patches to the third party source in Chromium for libjpeg [4] and libjpeg-turbo [5] however are available.
