Description Huzaifa S. Sidhpurwala 2015-08-11 02:22:06 EDT
An anonymous researcher reported, via TippingPoint's Zero Day Initiative, reported two integer overflows that could be triggered by a malicious 'saio' chunk in an MPEG4 video, leading to potential arbitrary code execution. This issue was independently reported by security researcher laf.intel

Security researcher Massimiliano Tomassoli discovered an integer overflow issue when parsing an invalid MPEG4 video.

Mozilla security engineer Tyson Smith used the Address Sanitizer to find a buffer overflow when parsing an MPEG4 video with an invalid size in an ESDS chunk lead to memory corruption.

Each of these reported issues result in potentially exploitable crashes that could allow for remote code execution.

Red Hat would like to thank the Mozilla project for reporting this issue. Upstream acknowledges Massimiliano Tomassoli, laf.intel, Massimiliano Tomassoli and Tyson Smith as the original reporter.
