Updated libjpeg packages fix security vulnerabilities:
libjpeg 6b and libjpeg-turbo will use uninitialized memory when decoding images with missing SOS data for the luminance component (Y) in presence of valid chroma data (Cr, Cb) (CVE-2013-6629).
libjpeg-turbo will use uninitialized memory when handling Huffman tables (CVE-2013-6630).
