Security researcher Arthur Gerkis used the Address Sanitizer
tool to find two issues involving Scalable Vector Graphics (SVG) files. The
first issue is a buffer overflow in Gecko's SVG filter code when the sum of two
values is too large to be stored as a signed 32-bit integer, causing the
function to write past the end of an array. The second issue is a use-after-free
when an element with a 'requiredFeatures' attribute is moved between documents.
In that situation, the internal representation of the 'requiredFeatures' value
could be freed prematurely. Both issues are potentially exploitable.");
