Xpdf Multiple Vulnerabilities

Multiple vulnerabilities have been identified in Xpdf, which could be exploited by attackers to compromise a vulnerable 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.
