Multiple vulnerabilities have been identified in Xpdf, which could be exploited by attackers to cause a denial of service or compromise a vulnerable system.
The first issue is caused by an array indexing error in the "DCTStream::readProgressiveDataUnit()" [xpdf/Stream.cc] method, which could be exploited by attackers to corrupt memory by tricking a user into opening a specially crafted PDF file.
The second vulnerability is caused by an integer overflow error in the "DCTStream::reset()" [xpdf/Stream.cc] method, which could be exploited by attackers to cause a heap overflow via a specially crafted PDF file.
The third issue is caused by a heap overflow error in the "CCITTFaxStream::lookChar()" [xpdf/Stream.cc] method, which could be exploited by attackers to execute arbitrary code by tricking a user into opening a PDF file containing a specially crafted "CCITTFaxDecode" filter.
