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 ove…

GStreamer is a library for constructing graphs of media-handling components. A null pointer dereference vulnerability has been discovered in the gst_matroska_demux_update_tracks function within matroska-demux.c. The vulnerability occurs when the gst_caps_is_equal function is called with invalid caps values. If this happen, then in the function gst_buffer_get_size the call to GST_BUFFER_MEM_PTR can return a null pointer. Attempting to dereference the size field of this null pointer results in a null pointer dereference. This vulnerability is fixed in 1.24.10.

GStreamer is a library for constructing graphs of media-handling components. A null pointer dereference vulnerability has been discovered in the gst_matroska_demux_add_wvpk_header function within matroska-demux.c. This function does not properly check the validity of the stream->codec_priv pointer in the following code. If stream->codec_priv is NULL, the call to GST_READ_UINT16_LE will attempt to dereference a null pointer, leading to a crash of the application. This vulnerability is fixed in 1.24.10.

GStreamer is a library for constructing graphs of media-handling components. A null pointer dereference vulnerability has been discovered in the gst_matroska_demux_parse_blockgroup_or_simpleblock function within matroska-demux.c. This function does not properly check the validity of the GstBuffer *sub pointer before performing dereferences. As a result, null pointer dereferences may occur. This vulnerability is fixed in 1.24.10.

GStreamer is a library for constructing graphs of media-handling components. An OOB-read vulnerability has been detected in the format_channel_mask function in gst-discoverer.c. The vulnerability affects the local array position, which is defined with a fixed size of 64 elements. However, the function gst_discoverer_audio_info_get_channels may return a guint channels value greater than 64. This causes the for loop to attempt access beyond the bounds of the position array, resulting in an OOB-read when an index greater than 63 is used. This vulnerability can result in reading unintended bytes from the stack. Additionally, the dereference of value->value_nick after the OOB-read can lead to further memory corruption or undefined behavior. This vulnerability is fixed in 1.24.10.

GStreamer is a library for constructing graphs of media-handling components. A null pointer dereference vulnerability has been discovered in the gst_jpeg_dec_negotiate function in gstjpegdec.c. This function does not check for a NULL return value from gst_video_decoder_set_output_state. When this happens, dereferences of the outstate pointer will lead to a null pointer dereference. This vulnerability can result in a Denial of Service (DoS) by triggering a segmentation fault (SEGV). This vulnerability is fixed in 1.24.10.

GStreamer is a library for constructing graphs of media-handling components. An OOB-read vulnerability has been discovered in the qtdemux_merge_sample_table function within qtdemux.c. The problem is that the size of the stts buffer isn’t properly checked before reading stts_duration, allowing the program to read 4 bytes beyond the boundaries of stts->data. This vulnerability reads up to 4 bytes past the allocated bounds of the stts array. This vulnerability is fixed in 1.24.10.

GStreamer is a library for constructing graphs of media-handling components. An OOB-read has been detected in the function qtdemux_parse_samples within qtdemux.c. This issue arises when the function qtdemux_parse_samples reads data beyond the boundaries of the stream->stco buffer. The following code snippet shows the call to qt_atom_parser_get_offset_unchecked, which leads to the OOB-read when parsing the provided GHSL-2024-245_crash1.mp4 file. This issue may lead to read up to 8 bytes out-of-bounds. This vulnerability is fixed in 1.24.10.

GStreamer is a library for constructing graphs of media-handling components. An OOB-read has been discovered in the qtdemux_parse_svq3_stsd_data function within qtdemux.c. In the FOURCC_SMI_ case, seqh_size is read from the input file without proper validation. If seqh_size is greater than the remaining size of the data buffer, it can lead to an OOB-read in the following call to gst_buffer_fill, which internally uses memcpy. This vulnerability can result in reading up to 4GB of process memory or potentially causing a segmentation fault (SEGV) when accessing invalid memory. This vulnerability is fixed in 1.24.10.

GStreamer is a library for constructing graphs of media-handling components. An integer underflow has been detected in extract_cc_from_data function within qtdemux.c. In the FOURCC_c708 case, the subtraction atom_length - 8 may result in an underflow if atom_length is less than 8. When that subtraction underflows, *cclen ends up being a large number, and then cclen is passed to g_memdup2 leading to an out-of-bounds (OOB) read. This vulnerability is fixed in 1.24.10.
