Information disclosure through polygon rendering in MathML — Mozilla

Security researcher Tyson Smith and Jesse Schwartzentruber of the BlackBerry Security Automated Analysis Team used the Address Sanitizer tool while fuzzing to discover an out-of-bounds read during polygon rendering in MathML. This can allow web content to potentially read protected memory addresses. In combination with previous techniques used for SVG timing attacks, this could allow for text values to be read across domains, leading to information disclosure.
