SVG issues found with Address Sanitizer — Mozilla

Security researcher Atte Kettunen from OUSPG found two issues with Firefox’s handling of SVG using the Address Sanitizer tool. The first issue, critically rated, is a use-after-free in SVG animation that could potentially lead to arbitrary code execution. The second issue is rated moderate and is an out of bounds read in SVG Filters. This could potentially incorporate data from the user’s memory, making it accessible to the page content.
