+From f457207b57d0e234cf7a174d20a7db424b82173d Mon Sep 17 00:00:00 2001
+From: mancha <mancha1@hush.com>
+Date: Fri, 22 Nov 2013
+Subject: CVE-2013-6629
+
+get_sos() in jdmarker.c does not check for duplication of component data
+while reading segments following Start Of Scan (SOS) JPEG markers. This
+allows remote attackers to obtain sensitive information from uninitialized
+memory locations via crafted JPEG images.

+# The "handy ruler" below makes it easier to edit a package description.  Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in.  You must

+libjpeg: libjpeg (Independent JPEG Group's JPEG software)
+libjpeg:
+libjpeg: Software to implement JPEG image compression and decompression.  JPEG
+libjpeg: (pronounced 'jay-peg') is a standardized compression method for
+libjpeg: full-color and gray-scale images.  JPEG is intended for compressing
+libjpeg: 'real-world' scenes; cartoons and other non-realistic images are not
+libjpeg: its strong suit.  JPEG is lossy, however, on typical images of
+libjpeg: real-world scenes, very good compression levels can be obtained with
+libjpeg: no visible change, and amazingly high compression levels are possible
+libjpeg: if you can tolerate a low-quality image.
