Description Tomas Hoger 2014-10-10 08:55:37 UTC
Chrome version 38.0.2125.101 fixes two flaws in the embedded PDF viewer PDFium:

CVE-2014-3189

The chrome_pdf::CopyImage function in pdf/draw_utils.cc in the PDFium component in Google Chrome before 38.0.2125.101 does not properly validate image-data dimensions, which allows remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via unknown vectors.

CVE-2014-3198

The Instance::HandleInputEvent function in pdf/instance.cc in the PDFium component in Google Chrome before 38.0.2125.101 interprets a certain -1 value as an index instead of a no-visible-page error code, which allows remote attackers to cause a denial of service (out-of-bounds read) via unspecified vectors.
