Can you explain this vulnerability to me?
This vulnerability is a stack overflow issue that was addressed by improving input validation in affected Apple operating systems.
A stack overflow occurs when a program writes more data to a buffer located on the stack than what is actually allocated, which can lead to unexpected behavior or crashes.
In this case, the vulnerability could allow an app to cause a denial-of-service condition.
How can this vulnerability impact me? :
