A Null Pointer Dereference vulnerability in WLAvalancheService component of Ivanti Avalanche before 6.4.3 allows an authenticated remote attacker to perform denial of service attacks.

An issue was discovered in Libreswan 3.x and 4.x before 4.12. When an IKEv1 ISAKMP SA Informational Exchange packet contains a Delete/Notify payload followed by further Notifies that act on the ISAKMP SA, such as a duplicated Delete/Notify message, a NULL pointer dereference on the deleted state causes the pluto daemon to crash and restart.

An issue was discovered in OpenNDS Captive Portal before version 10.1.2. It has a NULL pointer dereference in preauthenticated() that can be triggered with a crafted GET HTTP request with a missing redirect query string parameter. Triggering this issue results in crashing OpenNDS (a Denial-of-Service condition). Affected OpenNDS Captive Portal before version 10.1.2 fixed infixed in OpenWrt master, OpenWrt 23.05 and OpenWrt 22.03 on28. August 2023 by updating OpenNDS to version 10.1.3.

It was found that an attacker could issue a xattr request via glusterfs FUSE to cause gluster brick process to crash which will result in a remote denial of service. If gluster multiplexing is enabled this will result in a crash of multiple bricks and gluster volumes.

moby v25.0.0 - v26.0.2 is vulnerable to NULL Pointer Dereference via daemon/images/image_history.go.

Tensorflow is an Open Source Machine Learning Framework. When decoding a tensor from protobuf, TensorFlow might do a null-dereference if attributes of some mutable arguments to some operations are missing from the proto. This is guarded by a `DCHECK`. However, `DCHECK` is a no-op in production builds and an assertion failure in debug builds. In the first case execution proceeds to the dereferencing of the null pointer, whereas in the second case it results in a crash due to the assertion failure. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, and TensorFlow 2.6.3, as these are also affected and still in supported range.

Amcrest cameras and NVR are vulnerable to a null pointer dereference over port 37777. An authenticated remote attacker can abuse this issue to crash the device.
