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.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs no privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity high, availability high.

CVSS metrics in full

The score comes from this vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

  • Attack vector: Network — reachable from anywhere that can route to the service.

  • Privileges required: None — an unauthenticated stranger can try it.
  • User interaction: None — nobody has to be tricked into anything.
  • Scope: Unchanged — the damage stays inside the vulnerable component.
  • Confidentiality impact: High — total loss, or loss the attacker controls.
  • Integrity impact: High — total loss, or loss the attacker controls.
  • Availability impact: High — total loss, or loss the attacker controls.
