    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2024-47834:
    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->codec_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.

    CVE-2024-47778:
    GStreamer is a library for constructing graphs of media-handling components. An OOB-read vulnerability has
    been discovered in gst_wavparse_adtl_chunk within gstwavparse.c. This vulnerability arises due to
    insufficient validation of the size parameter, which can exceed the bounds of the data buffer. As a
    result, an OOB read occurs in the following while loop. 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.

    CVE-2024-47777:
    GStreamer is a library for constructing graphs of media-handling components. An OOB-read vulnerability has
    been identified in the gst_wavparse_smpl_chunk function within gstwavparse.c. This function attempts to
    read 4 bytes from the data + 12 offset without checking if the size of the data buffer is sufficient. If
    the buffer is too small, the function reads beyond its bounds. This vulnerability may result in reading 4
    bytes out of the boundaries of the data buffer. This vulnerability is fixed in 1.24.10.

    CVE-2024-47776:
    GStreamer is a library for constructing graphs of media-handling components. An OOB-read has been
    discovered in gst_wavparse_cue_chunk within gstwavparse.c. The vulnerability happens due to a discrepancy
    between the size of the data buffer and the size value provided to the function. This mismatch causes the
    comparison  if (size < 4 + ncues * 24) to fail in some cases, allowing the subsequent loop to access
    beyond the bounds of the data buffer. The root cause of this discrepancy stems from a miscalculation when
    clipping the chunk size based on upstream data size. This vulnerability allows reading beyond the bounds
    of the data buffer, potentially leading to a crash (denial of service) or the leak of sensitive data. This
    vulnerability is fixed in 1.24.10.

    CVE-2024-47775:
    GStreamer is a library for constructing graphs of media-handling components. An OOB-read vulnerability has
    been found in the parse_ds64 function within gstwavparse.c. The parse_ds64 function does not check that
    the buffer buf contains sufficient data before attempting to read from it, doing multiple
    GST_READ_UINT32_LE operations without performing boundary checks. This can lead to an OOB-read when buf is
    smaller than expected. This vulnerability allows reading beyond the bounds of the data buffer, potentially
    leading to a crash (denial of service) or the leak of sensitive data. This vulnerability is fixed in
    1.24.10.

    CVE-2024-47774:
    GStreamer is a library for constructing graphs of media-handling components. An OOB-read vulnerability has
    been identified in the gst_avi_subtitle_parse_gab2_chunk function within gstavisubtitle.c. The function
    reads the name_length value directly from the input file without checking it properly. Then, the a
    condition, does not properly handle cases where name_length is greater than 0xFFFFFFFF - 17, causing an
    integer overflow. In such scenario, the function attempts to access memory beyond the buffer leading to an
    OOB-read. This vulnerability is fixed in 1.24.10.

    CVE-2024-47613:
    GStreamer is a library for constructing graphs of media-handling components. A stack-buffer overflow has
    been detected in the vorbis_handle_identification_packet function within gstvorbisdec.c. The position
    array is a stack-allocated buffer of size 64. If vd->vi.channels exceeds 64, the for loop will write
    beyond the boundaries of the position array. The value written will always be
    GST_AUDIO_CHANNEL_POSITION_NONE. This vulnerability allows to overwrite the EIP address allocated in the
    stack. Additionally, this bug can overwrite the GstAudioInfo info structure. This vulnerability is fixed
    in 1.24.10.

    CVE-2024-47606:
    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.

    CVE-2024-47603:
    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.

    CVE-2024-47602:
    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.

    CVE-2024-47601:
    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.

    CVE-2024-47599:
    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.

    CVE-2024-47598:
    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 isnt 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.

    CVE-2024-47597:
    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.

    CVE-2024-47596:
    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.

    CVE-2024-47546:
    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.

    CVE-2024-47545:
    GStreamer is a library for constructing graphs of media-handling components. An integer underflow has been
    detected in qtdemux_parse_trak function within qtdemux.c. During the strf parsing case, the subtraction
    size -= 40 can lead to a negative integer overflow if it is less than 40. If this happens, the subsequent
    call to gst_buffer_fill will invoke memcpy with a large tocopy size, resulting in an OOB-read. This
    vulnerability is fixed in 1.24.10.

    CVE-2024-47544:
    GStreamer is a library for constructing graphs of media-handling components. The function
    qtdemux_parse_sbgp in qtdemux.c is affected by a null dereference vulnerability. This vulnerability is
    fixed in 1.24.10.

    CVE-2024-47543:
    GStreamer is a library for constructing graphs of media-handling components. An OOB-read vulnerability has
    been discovered in qtdemux_parse_container function within qtdemux.c. In the parent function
    qtdemux_parse_node, the value of length is not well checked. So, if length is big enough, it causes the
    pointer end to point beyond the boundaries of buffer. Subsequently, in the qtdemux_parse_container
    function, the while loop can trigger an OOB-read, accessing memory beyond the bounds of buf. 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.

    CVE-2024-47540:
    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.

    CVE-2024-47539:
    GStreamer is a library for constructing graphs of media-handling components. An out-of-bounds write
    vulnerability was identified in the convert_to_s334_1a function in isomp4/qtdemux.c. The vulnerability
    arises due to a discrepancy between the size of memory allocated to the storage array and the loop
    condition i * 2 < ccpair_size. Specifically, when ccpair_size is even, the allocated size in storage does
    not match the loop's expected bounds, resulting in an out-of-bounds write. This bug allows for the
    overwriting of up to 3 bytes beyond the allocated bounds of the storage array. This vulnerability is fixed
    in 1.24.10.

    CVE-2024-47537:
    GStreamer is a library for constructing graphs of media-handling components. The program attempts to
    reallocate the memory pointed to by stream->samples to accommodate stream->n_samples + samples_count
    elements of type QtDemuxSample. The problem is that samples_count is read from the input file. And if this
    value is big enough, this can lead to an integer overflow during the addition. As a consequence,
    g_try_renew might allocate memory for a significantly smaller number of elements than intended. Following
    this, the program iterates through samples_count elements and attempts to write samples_count number of
    elements, potentially exceeding the actual allocated memory size and causing an OOB-write. This
    vulnerability is fixed in 1.24.10.
