Descriptions

The FoFiType1::parse function in fofi/FoFiType1.cc in Xpdf 3.0.0, gpdf 2.8.2, kpdf in kdegraphics 3.3.1, and possibly other libraries and versions, does not check the return value of the getNextLine function, which allows context-dependent attackers to execute arbitrary code via a PDF file with a crafted Type 1 font that can produce a negative value, leading to a signed-to-unsigned integer conversion error and a buffer overflow.

La función FoFiType1::parse en fofi/FoFiType1.cc en Xpdf v3.0.0, en gpdf v2.8.2, en kpdf en kdegraphics v3.3.1, y posiblemente otras liberías y versiones, no verifica el valor de retorno de la función getNextLine, permite a los atacantes dependientes del contexto ejecutar código de su elección mediante un fichero PDF con una fuente Type 1 modificada que puede producir un valor negativo, conduciendo a un error de conversión de entero signed-to-unsigned y un desbordamiento de búfer.
