{"id":"ALPINE-CVE-2024-47606","details":"GStreamer is a library for constructing graphs of media-handling components. An integer underflow has been detected in the function qtdemux_parse_theora_extension within qtdemux.c. The vulnerability occurs due to an underflow of the gint size variable, which causes size to hold a large unintended value when cast to an unsigned integer. This 32-bit negative value is then cast to a 64-bit unsigned integer (0xfffffffffffffffa) in a subsequent call to gst_buffer_new_and_alloc. The function gst_buffer_new_allocate then attempts to allocate memory, eventually calling _sysmem_new_block. The function _sysmem_new_block adds alignment and header size to the (unsigned) size, causing the overflow of the 'slice_size' variable. As a result, only 0x89 bytes are allocated, despite the large input size. When the following memcpy call occurs in gst_buffer_fill, the data from the input file will overwrite the content of the GstMapInfo info structure. Finally, during the call to gst_memory_unmap, the overwritten memory may cause a function pointer hijack, as the mem-\u003eallocator-\u003emem_unmap_full function is called with a corrupted pointer. This function pointer overwrite could allow an attacker to alter the execution flow of the program, leading to arbitrary code execution. This vulnerability is fixed in 1.24.10.","modified":"2026-11-03T06:32:50.106815643Z","published":"2024-12-12T02:03:32.220Z","upstream":["CVE-2024-47606"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2024-47606"}],"affected":[{"package":{"name":"gst-plugins-good","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/gst-plugins-good?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.24.10-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2024-47606.json"}},{"package":{"name":"gst-plugins-good","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/gst-plugins-good?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.24.10-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2024-47606.json"}},{"package":{"name":"gst-plugins-good","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/gst-plugins-good?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.24.10-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2024-47606.json"}},{"package":{"name":"gst-plugins-good","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/gst-plugins-good?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.24.10-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2024-47606.json"}},{"package":{"name":"gst-plugins-good","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/gst-plugins-good?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.24.10-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2024-47606.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
