In Xpdf 4.01.01, a heap-based buffer over-read could be triggered in SampledFunction::transform in Function.cc when using a large index for samples. 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. In Xpdf versión 4.01.01, se podría desencadenar una lectura excesiva del búfer en la región heap de la memoria en la función en SampledFunction::transform en Function.cc cuando se utiliza un índice grande para muestras. Por ejemplo, puede activarse enviando un documento PDF elaborado a la herramienta pdftotext. • https://forum.xpdfreader.com/viewtopic.php?f=3&t=41842 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DJJD7X3ES7ZHJUY2R3DAVCJPV23R64VK https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/FWEWFUVITPA3Y6F4A5SJSROKYT7PRH7Q https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/TNIJWRYTCLGV35WGIHYTMMOPEEOOTIPT • CWE-125: Out-of-bounds Read •

In Xpdf 4.01.01, a heap-based buffer overflow could be triggered in DCTStream::decodeImage() in Stream.cc when writing to frameBuf memory. 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, an information leak, or possibly unspecified other impact. En Xpdf versión 4.01.01, se podría desencadenar una vulnerabilidad de desbordamiento de búfer basado en memoria dinámica (heap) en DCTStream::decodeImage() en Stream.cc cuando se escribe en la memoria frameBuf. Esto puede, por ejemplo, activarse mediante el envío de un documento PDF especialmente diseñado para la herramienta pdftotext tool. • https://forum.xpdfreader.com/viewtopic.php?f=3&t=41841 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DJJD7X3ES7ZHJUY2R3DAVCJPV23R64VK https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/FWEWFUVITPA3Y6F4A5SJSROKYT7PRH7Q https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/TNIJWRYTCLGV35WGIHYTMMOPEEOOTIPT • CWE-787: Out-of-bounds Write •

In Xpdf 4.01.01, a heap-based buffer over-read could be triggered in FoFiType1C::convertToType0 in fofi/FoFiType1C.cc when it is trying to access the second privateDicts array element, because the privateDicts array has only one element allocated. En Xpdf versión 4.01.01, se podría desencadenar una lectura excesiva del búfer en la región heap de la memoria en la función FoFiType1C::convertToType0 en el archivo fofi/FoFiType1C.cc cuando se intenta acceder al segundo elemento de la matriz privateDicts, debido a que la matriz privateDicts solo tiene un elemento asignado. • https://forum.xpdfreader.com/viewtopic.php?f=3&t=41815 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DJJD7X3ES7ZHJUY2R3DAVCJPV23R64VK https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/FWEWFUVITPA3Y6F4A5SJSROKYT7PRH7Q https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/TNIJWRYTCLGV35WGIHYTMMOPEEOOTIPT • CWE-125: Out-of-bounds Read •

In Xpdf 4.01.01, a buffer over-read could be triggered in FoFiType1C::convertToType1 in fofi/FoFiType1C.cc when the index number is larger than the charset array bounds. It can, for example, be triggered by sending a crafted PDF document to the pdftops 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. En Xpdf versión 4.01.01, una lectura excesiva del búfer podría activarse en la función FoFiType1C::convertToType1 en el archivo fofi/FoFiType1C.cc cuando el número de índice es mayor que los límites de la matriz charset.
