Name of the Vulnerable Software and Affected Versions
OpenThread (affected versions not specified)
Description
Multiple issues exist in the handling of Mesh Link Establishment (MLE) packets. An authenticated attacker on the same Thread network can send specially crafted packets to cause a denial of service. These issues involve triggerable assertion failures and a stack-based buffer overflow, which occurs when a program writes more data to a buffer located on the stack than the buffer is allocated to hold.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
