CVE-2017-7856
LibreOffice before 2017-03-11 has an out-of-bounds write caused by a heap-based buffer overflow in the SVMConverter::ImplConvertFromSVM1 function in vcl/source/gdi/svmconverter.cxx.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.49%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
