Description

In libtheora, a video's dimensions are multiplied together and used in particular memory allocations. When the video dimensions are sufficiently large, the multiplication could overflow a 32-bit integer resulting in too small a memory buffer being allocated for the video. An attacker could use a specially crafted video to write data past the bounds of this buffer, causing a crash and potentially executing arbitrary code.
