Descriptions

DOS / potential heap overwrite in mkv demuxing using zlib decompression. Integer overflow in matroskademux element in gst_matroska_decompress_data 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 / escritura excesiva potencial de pila en la demuxación de mkv usando descompresión zlib. Desbordamiento de enteros en el elemento matroskademux en la función gst_matroska_decompress_data 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 sistema operativo 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 zlib decompression. This vulnerability can result in application crash, memory corruption, and code execution.

GStreamer is a streaming media framework based on graphs of filters which operate on media data. The gstreamer1-plugins-good packages contain a collection of well-supported plug-ins of good quality and under the LGPL license. Issues addressed include a buffer overflow vulnerability.
