slackware
Calendar Grey December 17, 2013
Dist Slackware Esm H88
Updated libjpeg packages are now available for Slackware, rectifying a vulnerability related to uninitialized memory in image decoding processes.
New libjpeg packages are available for Slackware 13.0, 13.1, 13.37, 14.0, 14.1, and -current to fix a security issue

Summary

Here are the details from the Slackware 14.1 ChangeLog: patches/packages/libjpeg-v8a-i486-2_slack14.1.txz: Rebuilt. Fix use of uninitialized memory when decoding images with missing SOS data for the luminance component (Y) in presence of valid chroma data (Cr, Cb). This could allow remote attackers to obtain sensitive information from uninitialized memory locations via a crafted JPEG image.
