Junos OS: MX304, MX with MPC10/11/LC9600, and EX9200 with EX9200-15C: In a VPLS or Junos Fusion scenario specific show commands cause FPCs to crash
Summary
A NULL Pointer Dereference vulnerability in the
packet forwarding engine (pfe) of Juniper Networks Junos OS on MX304, MX with MPC10/11/LC9600, and EX9200 with EX9200-15C allows a locally authenticated attacker with low privileges to cause a Denial of Service (DoS).
In a VPLS or Junos Fusion scenario, the execution of specific show commands will cause all FPCs hosting VPLS sessions or connecting to satellites to crash and restart.
This issue affects Junos on MX304, MX with MPC10/11/LC9600 and EX9200 with EX9200-15C:
* All version before 21.2R3-S1,
* 21.3 versions before 21.3R3,
* 21.4 versions before 21.4R2.

GHSL-2024-235: GStreamer ID3v2 parser out-of-bounds read and NULL-pointer dereference
Summary
GStreamer is a library for constructing graphs of media-handling components. A null pointer dereference has been discovered in the id3v2_read_synch_uint function, located in id3v2.c. If id3v2_read_synch_uint is called with a null work->hdr.frame_data, the pointer guint8 *data is accessed without validation, resulting in 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.

NULL Pointer Dereference vulnerability in SAP NetWeaver Application Server for ABAP and ABAP Platform
Summary
SAP NetWeaver Application Server for ABAP and ABAP Platform allows an unauthenticated attacker to send a maliciously crafted http request which could cause a null pointer dereference in the kernel. This dereference will result in the system crashing and rebooting, causing the system to be temporarily unavailable. There is no impact on Confidentiality or Integrity.

Title
GHSL-2024-247: GStreamer Insufficient error handling in JPEG decoder that can lead to NULL-pointer dereferences
Summary
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.

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.

Title
GHSL-2024-251: GStreamer NULL-pointer dereference in Matroska/WebM demuxer
Summary
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.

Title
GHSL-2024-118: GStreamer has a null pointer dereference in gst_gdk_pixbuf_dec_flush
Summary
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-2024-263: Gstreamer NULL-pointer dereference in LRC subtitle parser
Summary
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.

Mitigation ID: MIT-56
Phase: Implementation
Description:
- For any pointers that could have been modified or provided from a function that can return NULL, check the pointer for NULL before use. When working with a multithreaded or otherwise asynchronous environment, ensure that proper locking APIs are used to lock before the check, and unlock when it has finished [REF-1484].
Mitigation
Phase: Requirements
Description:
- Select a programming language that is not susceptible to these issues.
Mitigation
Phase: Implementation
Description:
- Check the results of all functions that return a value and verify that the value is non-null before acting upon it.
Mitigation
Phase: Architecture and Design
Description:
- Identify all variables and data stores that receive information from external sources, and apply input validation to make sure that they are only initialized to expected values.
Mitigation
Phase: Implementation
Description:
- Explicitly initialize all variables and other data stores, either during declaration or just before the first usage.
