CVE-2024-47540 Information

Description

GStreamer is a library for constructing graphs of media-handling components. An uninitialized stack variable vulnerability has been identified in the gst_matroska_demux_add_wvpk_header function within matroska-demux.c. When size < 4 the program calls gst_buffer_unmap with an uninitialized map variable. Then in the gst_memory_unmap function the program will attempt to unmap the buffer using the uninitialized map variable causing a function pointer hijack as it will jump to mem->allocator->mem_unmap_full or mem->allocator->mem_unmap. This vulnerability could allow an attacker to hijack the execution flow potentially leading to code execution. This vulnerability is fixed in 1.24.10.
