{"id":"AZL-62402","summary":"CVE-2024-47834 affecting package gstreamer1 1.20.0-2","details":"GStreamer is a library for constructing graphs of media-handling components. An Use-After-Free read vulnerability has been discovered affecting the processing of CodecPrivate elements in Matroska streams. In the GST_MATROSKA_ID_CODECPRIVATE case within the gst_matroska_demux_parse_stream function, a data chunk is allocated using gst_ebml_read_binary. Later, the allocated memory is freed in the gst_matroska_track_free function, by the call to g_free (track-\u003ecodec_priv). Finally, the freed memory is accessed in the caps_serialize function through gst_value_serialize_buffer. The freed memory will be accessed in the gst_value_serialize_buffer function. This results in a UAF read vulnerability, as the function tries to process memory that has already been freed. This vulnerability is fixed in 1.24.10.","modified":"2026-04-01T05:20:04.361348Z","published":"2024-12-12T02:03:43Z","upstream":["CVE-2024-47834"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-47834"}],"affected":[{"package":{"name":"gstreamer1","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/gstreamer1"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"1.20.0-2"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-62402.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H"}]}
