4 | Subject: [PATCH] matroskademux: Initialize track context out parameter to NULL | ||
5 | before parsing | ||
6 | |||
7 | Various error return paths don't set it to NULL and callers are only | ||
8 | checking if the pointer is NULL. As it's allocated on the stack this | ||
9 | usually contains random stack memory, and more often than not the memory | ||
10 | of a previously parsed track. | ||
11 | |||
12 | This then causes all kinds of memory corruptions further down the line. | ||
13 | |||
