Uncovered by Google’s Threat Analysis Group scientists, Adam Weidemann and Clément Lecigne, very few information of the security flaw have been disclosed but UAF vulnerabilities normally aid attacks this sort of as arbitrary code execution and info corruption in unpatched software program, and can lead to the takeover of a victim’s machine.
UAF vulnerabilities relate to incorrect use of dynamic memory in software program. Dynamic memory allocation is applied by programmers to store significant amounts of info inside functioning program and blocks of info are reallocated frequently.
Programmes use headers to look at which sections of dynamic memory are absolutely free and UAF vulnerabilities can be exploited when programmes do not take care of these headers appropriately. These flaws allow an attacker to substitute code in area of cleared data in dynamic memory if a pointer is not cleared right after facts is moved to a different block.
