Several vulnerabilities have been discovered in xpdf code that is
embedded in koffice, an integrated office suite for KDE. These flaws
could allow an attacker to execute arbitrary code by inducing the user

and Exposures project identifies the following problems :
Array index error in the
DCTStream::readProgressiveDataUnit method in
xpdf/Stream.cc in Xpdf 3.02pl1, as used in poppler,
teTeX, KDE, KOffice, CUPS, and other products, allows
remote attackers to trigger memory corruption and
execute arbitrary code via a crafted PDF file.
Integer overflow in the DCTStream::reset method in
xpdf/Stream.cc in Xpdf 3.02p11 allows remote attackers
to execute arbitrary code via a crafted PDF file,
resulting in a heap-based buffer overflow.
Heap-based buffer overflow in the
CCITTFaxStream::lookChar method in xpdf/Stream.cc in
Xpdf 3.02p11 allows remote attackers to execute
arbitrary code via a PDF file that contains a crafted
