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.

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.

Title
Junos OS: MX Series: The PFE will crash on running specific command
Summary
A NULL Pointer Dereference vulnerability in the Packet Forwarding Engine (pfe) of Juniper Networks Junos OS allows a local, low-privileged attacker to cause a Denial-of-Service (DoS).
When a specific command is executed, the pfe crashes. This will cause traffic forwarding to be interrupted until the system self-recovers. Repeated execution will create a sustained DoS condition.
This issue only affects MX Series devices with Line cards MPC1-MPC9.
This issue affects:
Junos OS on MX Series:
* All versions before 21.4R3-S9,
* from 22.2 before 22.2R3-S5,
* from 22.3 before 22.3R3-S4,
* from 22.4 before 22.4R3-S2,
* from 23.2 before 23.2R2-S1,
* from 23.4 before 23.4R2.

Mitigation MIT-56
Implementation
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
Requirements
Select a programming language that is not susceptible to these issues.
Mitigation
Implementation
Check the results of all functions that return a value and verify that the value is non-null before acting upon it.
Mitigation
Architecture and Design
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
Implementation
Explicitly initialize all variables and other data stores, either during declaration or just before the first usage.
