Description


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.

NOTE: An integer overflow error in "ImageStream::ImageStream()" which results in a crash has also been reported.

The vulnerabilities are reported in versions prior to 3.02pl4.
