CVE-2019-12493
Published: 31 May 2019
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.

| ebarretto | Marking emscripten ignored as poppler code is only for test/example. since 0.5.12-1 libextractor does not use xpdf anymore. xpdf in Debian uses poppler, which is not affected or fixed |
