CVE-2019-12493 (CCN-161869)

Assigned:2019-05-28
Published:2019-05-28
Updated:2019-09-30
Summary: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.
