GHSL-2024-263: Gstreamer NULL-pointer dereference in LRC subtitle parser

GStreamer is a library for constructing graphs of media-handling components. A null pointer dereference vulnerability has been detected in the parse_lrc function within gstsubparse.c. The parse_lrc function calls strchr() to find the character ']' in the string line. The pointer returned by this call is then passed to g_strdup(). However, if the string line does not contain the character ']', strchr() returns NULL, and a call to g_strdup(start + 1) leads to a null pointer dereference. This vulnerability is fixed in 1.24.10.

gstreamer-plugins-bad-free: Missing initialization of allocated heap memory leads to information leak

The vmnc decoder in the gstreamer does not initialize the render canvas, which allows remote attackers to obtain sensitive information as demonstrated by thumbnailing a simple 1 frame vmnc movie that does not draw to the allocated render canvas.

An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-21443.

gstreamer: Out-of-bounds read in gst_date_time_new_from_iso8601_string()

The gst_date_time_new_from_iso8601_string function in gst/gstdatetime.c in GStreamer before 1.10.3 allows remote attackers to cause a denial of service (out-of-bounds heap read) via a malformed datetime string.

gstreamer-plugins-good: Heap out-of-bounds read in gst_avi_demux_parse_ncdt

The gst_avi_demux_parse_ncdt function in gst/avi/gstavidemux.c in gst-plugins-good in GStreamer before 1.10.3 allows remote attackers to cause a denial of service (out-of-bounds heap read) via vectors involving ncdt tags.

GHSL-2024-115: GStreamer has a stack-buffer overflow in vorbis_handle_identification_packet

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 someone 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.

GHSL-2024-245: GStreamer has an OOB-read in qtdemux_parse_samples

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.

GHSL-2024-250: Streamer NULL-pointer dereferences and out-of-bounds reads in Matroska/WebM demuxer

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.

GHSL-2024-118: GStreamer has a null pointer dereference in gst_gdk_pixbuf_dec_flush

GStreamer is a library for constructing graphs of media-handling components. A null pointer dereference vulnerability has been identified in `gst_gdk_pixbuf_dec_flush` within `gstgdkpixbufdec.c`. This function invokes `memcpy`, using `out_pix` as the destination address. `out_pix` is expected to point to the frame 0 from the frame structure, which is read from the input file. However, in certain situations, it can points to a NULL frame, causing the subsequent call to `memcpy` to attempt writing to the null address (0x00), leading 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.

GHSL-2024-117: GStreamer has an out-of-bounds write in Ogg demuxer

GStreamer is a library for constructing graphs of media-handling components. An OOB-Write has been detected in the function gst_parse_vorbis_setup_packet within vorbis_parse.c. The integer size is read from the input file without proper validation. As a result, size can exceed the fixed size of the pad->vorbis_mode_sizes array (which size is 256). When this happens, the for loop overwrites the entire pad structure with 0s and 1s, affecting adjacent memory as well. This OOB-write can overwrite up to 380 bytes of memory beyond the boundaries of the pad->vorbis_mode_sizes array. This vulnerability is fixed in 1.24.10.

GHSL-2024-258: GStreamer has an OOB-read in gst_wavparse_adtl_chunk

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.

gstreamer-plugins-good: Invalid memory read in gst_aac_parse_sink_setcaps

The gst_aac_parse_sink_setcaps function in gst/audioparsers/gstaacparse.c in gst-plugins-good in GStreamer before 1.10.3 allows remote attackers to cause a denial of service (invalid memory read and crash) via a crafted audio file.

GHSL-2024-197: GStreamer uses uninitialized stack memory in Matroska/WebM demuxer

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.

GHSL-2024-280: Gstreamer Use-After-Free read in Matroska CodecPrivate

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.

GStreamer Incorrect Permission Assignment Local Privilege Escalation Vulnerability

GStreamer Incorrect Permission Assignment Local Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of GStreamer. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the product installer. The issue results from incorrect permissions on folders. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of a target user. Was ZDI-CAN-25448.

GHSL-2024-094: GStreamer has an OOB-write in isomp4/qtdemux.c

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.

The gst_asf_demux_process_ext_content_desc function in gst/asfdemux/gstasfdemux.c in gst-plugins-ugly in GStreamer allows remote attackers to cause a denial of service (out-of-bounds heap read) via vectors involving extended content descriptors.

gstreamer-plugins-bad-free: Memory corruption flaw in NSF decoder

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.

gstreamer-plugins-base: Stack overflow in gst_riff_create_audio_caps

The gst_riff_create_audio_caps function in gst-libs/gst/riff/riff-media.c in gst-plugins-base in GStreamer before 1.10.3 does not properly limit recursion, which allows remote attackers to cause a denial of service (stack overflow and crash) via vectors involving nested WAVEFORMATEX.
