A stack-based buffer over-read exists in PostScriptFunction::transform in Function.cc in Xpdf 4.01.01 because GfxSeparationColorSpace and GfxDeviceNColorSpace mishandle tint transform functions. It can, for example, be triggered by sending a crafted PDF document to the pdftops tool. It might allow an attacker to cause Denial of Service or leak memory data. Existe una sobre-lectura del búfer basado en la pila en PostScriptFunction :: transform en Function.cc en Xpdf 4.01.01 porque GfxSeparationColorSpace y GfxDeviceNColorSpace maneja de forma incorrecta tint transform funciona. Por ejemplo, puede activarse enviando un documento PDF elaborado a la herramienta pdftops. • https://forum.xpdfreader.com/viewtopic.php?f=3&t=41806 https://lists.debian.org/debian-lts-announce/2019/09/msg00033.html 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 •
