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.
 For more information, see:

 (* Security fix *)
+--------------------------+");
