CVE-2017-17821

Priority
Description
WTF/wtf/FastBitVector.h in WebKit, as distributed in Safari Technology
Preview Release 46, allows remote attackers to cause a denial of service
(buffer overflow) or possibly have unspecified other impact because it
calls the FastBitVectorWordOwner::resizeSlow function (in
WTF/wtf/FastBitVector.cpp) for a purpose other than initializing a
bitvector size, and resizeSlow mishandles cases where the old array length
is greater than the new array length.
Notes
jdstrandwebkit receives limited support. For details, see
https://wiki.ubuntu.com/SecurityTeam/FAQ#webkit
webkit in Ubuntu uses the JavaScriptCore (JSC) engine, not V8
