Some vulnerabilities have been reported in Xpdf, which can be
exploited by malicious people to potentially compromise a user's
system.
1) Multiple integer overflows in "SplashBitmap::SplashBitmap()"
can be exploited to cause heap-based buffer overflows.
2) An integer overflow error in "ObjectStream::ObjectStream()"
can be exploited to cause a heap-based buffer overflow.
3) Multiple integer overflows in "Splash::drawImage()" can be
exploited to cause heap-based buffer overflows.
4) An integer overflow error in "PSOutputDev::doImageL1Sep()"
can be exploited to cause a heap-based buffer overflow when
converting a PDF document to a PS file.
Successful exploitation of the vulnerabilities may allow execution
of arbitrary code by tricking a user into opening a specially crafted
PDF file.
