{"id":"CVE-2024-47540","state":"PUBLISHED","title":"GHSL-2024-197: GStreamer uses uninitialized stack memory in Matroska/WebM demuxer","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.","publishedAt":"2024-12-11T18:54:04.383Z","updatedAt":"2025-11-03T20:39:37.616Z","severity":{"score":8.6,"label":"High","version":"4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["gstreamer gstreamer"],"affected":[{"vendor":"gstreamer","product":"gstreamer","versions":[{"version":"< 1.24.10","status":"affected"}]}],"references":["https://securitylab.github.com/advisories/GHSL-2024-197_GStreamer/","https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/8057.patch","https://gstreamer.freedesktop.org/security/sa-2024-0017.html","https://lists.debian.org/debian-lts-announce/2025/02/msg00035.html"],"weaknesses":["CWE-457"],"ingestedAt":"2026-10-29T20:07:56.516Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2024/47xxx/CVE-2024-47540.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2024-47540","state":"PUBLISHED","datePublished":"2024-12-11T18:54:04.383Z","dateUpdated":"2025-11-03T20:39:37.616Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2024-09-25T21:46:10.930Z"},"containers":{"cna":{"title":"GHSL-2024-197: GStreamer uses uninitialized stack memory in Matroska/WebM demuxer","descriptions":[{"lang":"en","value":"GStreamer is a library for constructing graphs of media-handling components.
