CVE-2016-3740

Estado: ModificadaAlta (7.8)—

Heap-based buffer overflow in the CreateFXPDFConvertor function in ConvertToPdf_x86.dll in Foxit Reader 7.3.4.311 allows remote attackers to execute arbitrary code via a large SamplesPerPixel value in a crafted TIFF image that is mishandled during PDF conversion. This is fixed in 8.0.

CVSS

Probabilidad de explotación (EPSS)
