Vulnerability Assessment & Network Security Forums
If through a vulnerability assessment, a network security issue is detected for the vulnerability below, applying the appropriate security patches in a timely matter is very important. If you have detected that your system has already been compromised, following CERT's Network Security recovery document will assist with recommended steps for system recovery.
Vulnerability Assessment Details
Check for the version of the kdegraphics package
Detailed Explanation for this Vulnerability Assessment
The remote host is missing the patch for the advisory MDKSA-2006:012 (kdegraphics).
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, permit 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 permits 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
permits 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) Kdegraphics uses an embedded copy of the
xpdf code, with the same vulnerabilities. The updated packages have been
patched to correct these problems.
