Descriptions
DOS / potential heap overwrite in mkv demuxing using lzo decompression. Integer overflow in matroskademux element in lzo decompression function which causes a segfault, or could cause a heap overwrite, depending on libc and OS. Depending on the libc used, and the underlying OS capabilities, it could be just a segfault or a heap overwrite. If the libc uses mmap for large chunks, and the OS supports mmap, then it is just a segfault (because the realloc before the integer overflow will use mremap to reduce the size of the chunk, and it will start to write to unmapped memory). However, if using a libc implementation that does not use mmap, or if the OS does not support mmap while using libc, then this could result in a heap overwrite.
DOS / sobreescritura potencial de heap en la demuxación de mkv usando descompresión lzo. Desbordamiento de enteros en el elemento matroskademux en la función de descompresión lzo que causa un segfault, o podría causar una escritura excesiva de la pila, dependiendo de la libc y el SO. Dependiendo de la libc usada, y de las capacidades del SO subyacente, podría ser sólo un segfault o una escritura excesiva de la pila. Si la libc usa mmap para los trozos grandes, y el SO soporta mmap, entonces es sólo un segfault (porque la reasignación antes del desbordamiento de enteros usará mremap para reducir el tamaño del trozo, y comenzará a escribir en la memoria no mapeada). Sin embargo, si es usada una implementación de libc que no usa mmap, o si el SO no soporta mmap mientras es usada libc, entonces esto podría resultar en una escritura excesiva de la pila.
A flaw was found in GStreamer. An integer overflow can lead to a heap-based buffer overflow in the mkv demuxer when processing a specially crafted Matroska/WebM file using lzo decompression. This vulnerability can result in application crash, memory corruption, and code execution.
