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.
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-2024-47540
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-2024-47606
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-2024-47613
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.
