Security patch from Martin Pitt (#5516). Multiple integer/buffer
overflows.
* poppler/Stream.cc (CCITTFaxStream::CCITTFaxStream): Check
columns for negative or large values (CVE-2005-3624).
* poppler/Stream.cc: Reset numComps to 0 since it's a global
variable that is used later (CVE-2005-3627).
* poppler/Stream.cc (DCTStream::readHuffmanTables): Fix out of
bounds array access in Huffman tables (CVE-2005-3627).
* poppler/Stream.cc (DCTStream::readMarker): Check for EOF in
while loop to prevent endless loops (CVE-2005-3625).
* poppler/JBIG2Stream.cc (JBIG2Bitmap::JBIG2Bitmap,
JBIG2Bitmap::expand, JBIG2Stream::readHalftoneRegionSeg): Check
user supplied width and height against invalid values. Allocate
one extra byte to prevent out of bounds access in combine().
