Description:
Some vulnerabilities have been reported in Xpdf, which can be exploited by malicious people to compromise a user's system.
1) An integer overflow within "StreamPredictor::StreamPredictor()" in xpdf/Stream.cc can be exploited to cause a heap-based buffer overflow by e.g. tricking a user into opening a specially crafted PDF file in Xpdf.
2) A boundary error within "StreamPredictor::getNextLine()" in xpdf/Stream.cc can be exploited to cause a stack-based buffer overflow by e.g. tricking a user into opening a specially crafted PDF file in Xpdf.
The vulnerabilities are confirmed in version 3.02. Other versions may also be affected.
Solution:
Apply patch xpdf-3.02pl1.patch.
