Mandriva Linux Security Advisory MDKSA-2006:005
http://www.mandriva.com/security/
_______________________________________________________________________
Package : xpdf
Date : January 5, 2006
Affected: 2006.0, Corporate 2.1, Corporate 3.0
_______________________________________________________________________
Problem Description:
Multiple heap-based buffer overflows in the
DCTStream::readProgressiveSOF and DCTStream::readBaselineSOF functions
in the DCT stream parsing code (Stream.cc) in xpdf 3.01 and earlier,
allow user-complicit attackers to cause a denial of service (heap
corruption) and possibly execute arbitrary code via a crafted PDF file
with an out-of-range number of components (numComps), which is used as
an array index. (CVE-2005-3191)
Heap-based buffer overflow in the StreamPredictor function in Xpdf 3.01
allows remote attackers to execute arbitrary code via a PDF file with
an out-of-range numComps (number of components) field. (CVE-2005-3192)
Heap-based buffer overflow in the JPXStream::readCodestream function
in the JPX stream parsing code (JPXStream.c) for xpdf 3.01 and earlier
allows user-complicit attackers to cause a denial of service (heap
corruption) and possibly execute arbitrary code via a crafted PDF file
with large size values that cause insufficient memory to be allocated.
(CVE-2005-3193)
An additional patch re-addresses memory allocation routines in
goo/gmem.c (Martin Pitt/Canonical, Dirk Mueller/KDE).
In addition, Chris Evans discovered several other vulnerbilities in
the xpdf code base:
Out-of-bounds heap accesses with large or negative parameters to
"FlateDecode" stream. (CVE-2005-3192)
Out-of-bounds heap accesses with large or negative parameters to
"CCITTFaxDecode" stream. (CVE-2005-3624)
Infinite CPU spins in various places when stream ends unexpectedly.
(CVE-2005-3625)
NULL pointer crash in the "FlateDecode" stream. (CVE-2005-3626)
Overflows of compInfo array in "DCTDecode" stream. (CVE-2005-3627)
Possible to use index past end of array in "DCTDecode" stream.
(CVE-2005-3627)
Possible out-of-bounds indexing trouble in "DCTDecode" stream.
(CVE-2005-3627)
The updated packages have been patched to correct these problems.
