Description Huzaifa S. Sidhpurwala 2012-06-03 09:01:50 UTC
Security researcher Abhishek Arya of Google used the Address Sanitizer tool to uncover several issues: two heap buffer overflow bugs and a use-after-free problem. The first heap buffer overflow was found in conversion from unicode to native character sets when the function fails. The use-after-free occurs in nsFrameList when working with column layout with absolute positioning in a container that changes size. The second buffer overflow occurs in nsHTMLReflowState when a window is resized on a page with nested columns and a combination of absolute and relative positioning. All three of these issues are potentially exploitable.
