An issue was discovered in Xpdf 4.01.01. There is an integer overflow in the function JBIG2Bitmap::combine at JBIG2Stream.cc for the "multiple bytes per line" case.
An issue was discovered in Xpdf 4.01.01. There is an Integer overflow in the function JBIG2Bitmap::combine at JBIG2Stream.cc for the "one byte per line" case.
In Xpdf 4.01.01, there is a heap-based buffer over-read in the function DCTStream::readScan() located at Stream.cc. It can, for example, be triggered by sending a crafted PDF document to the pdftops tool. It might allow an attacker to cause Information Disclosure.
In Xpdf 4.01.01, there is a use-after-free vulnerability in the function JBIG2Stream::close() located at JBIG2Stream.cc. It can, for example, be triggered by sending a crafted PDF document to the pdftoppm tool.
In Xpdf 4.01.01, the Parser::getObj() function in Parser.cc may cause infinite recursion via a crafted file. A remote attacker can leverage this for a DoS attack. This is similar to CVE-2018-16646.
In Xpdf 4.01.01, there is an out-of-bounds read vulnerability in the function SplashXPath::strokeAdjust() located at splash/SplashXPath.cc. It can, for example, be triggered by sending a crafted PDF document to the pdftoppm tool. It might allow an attacker to cause Information Disclosure. This is related to CVE-2018-16368.
In Xpdf 4.01.01, there is a heap-based buffer over-read in the function JBIG2Stream::readTextRegionSeg() located at JBIG2Stream.cc. It can, for example, be triggered by sending a crafted PDF document to the pdftoppm tool. It might allow an attacker to cause Information Disclosure.
In Xpdf 4.01.01, a heap-based buffer over-read could be triggered in strncpy from FoFiType1::parse in fofi/FoFiType1.cc because it does not ensure the source string has a valid length before making a fixed-length copy. It can, for example, be triggered by sending a crafted PDF document to the pdftotext tool. It allows an attacker to use a crafted pdf file to cause Denial of Service or an information leak, or possibly have unspecified other impact.
