Summary
An integer underflow was detected in GStreamer's qtdemux_parse_theora_extension function in qtdemux.c. This leads to an allocation size overflow, overwriting the GstMapInfo structure and potentially hijacking a function pointer, which may allow arbitrary code execution.
Risk Assessment
Processing a malicious media file may lead to arbitrary code execution in the context of the application using GStreamer, posing a serious risk to workstations and servers processing media.
Recommendation
Update GStreamer to version 1.24.10 or later and avoid processing untrusted media files until the patch is deployed.
Other vulnerabilities in GStreamer
See all- CVE-2026-17072Low
In GStreamer's gst-plugins-good, a heap-based out-of-bounds read of 4 bytes occurs when parsing FLAC audio stream headers embedded in Matroska or WebM container files. A boundary check does not account for the full size of the copied data, allowing a small read past the end of the allocated buffer. An attacker can exploit this by crafting a malicious Matroska or WebM file and tricking a user into opening it.
- CVE-2017-5843High
Multiple use-after-free vulnerabilities in the gst_mini_object_unref, gst_tag_list_unref, and gst_mxf_demux_update_essence_tracks functions in GStreamer before 1.10.3 allow remote attackers to cause a denial of service (crash) via vectors involving stream tags.
- CVE-2017-5840High
The qtdemux_parse_samples function in gst/isomp4/qtdemux.c in GStreamer before version 1.10.3 allows remote attackers to cause a denial of service (out-of-bounds heap read) via vectors involving the current stts index.
- CVE-2017-5838High
The gst_date_time_new_from_iso8601_string function in GStreamer before version 1.10.3 allows remote attackers to cause a denial of service via a malformed datetime string, leading to an out-of-bounds heap read.
- CVE-2016-9447High
The ROM mappings in the NSF decoder in gstreamer 0.10.x allow remote attackers to cause a denial of service (out-of-bounds read or write) and possibly execute arbitrary code via a crafted NSF music file.
- CVE-2016-9446High
The vmnc decoder in gstreamer does not initialize the render canvas, allowing remote attackers to obtain sensitive information. This is demonstrated by thumbnailing a simple 1 frame vmnc movie that does not draw to the allocated render canvas.
- CVE-2016-9445High
Integer overflow in the vmnc decoder in gstreamer allows remote attackers to cause a denial of service (crash) via large width and height values, which triggers a buffer overflow.
- CVE-2016-9809High
Off-by-one error in the gst_h264_parse_set_caps function in GStreamer before version 1.10.2 allows remote attackers to have unspecified impact via a crafted file, leading to an out-of-bounds read.
- CVE-2016-9808High
The FLIC decoder in GStreamer before 1.10.2 allows remote attackers to cause a denial of service (out-of-bounds write and crash) via a crafted series of skip and count pairs.
- CVE-2026-111183Critical
The rtpL16depay element in GStreamer has a heap-based buffer overflow due to missing validation of user-supplied data length before copying. This allows a remote attacker to execute arbitrary code in the context of the current process.
Original NVD description (English source)
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->allocator->mem_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.
