Published on June 23, 2023
Known Exploited Vulnerability
This Apple Multiple Products Integer Overflow Vulnerability is part of CISA's list of Known Exploited Vulnerabilities. Apple iOS. iPadOS, macOS, and watchOS contain an integer overflow vulnerability that could allow an application to execute code with kernel privileges.
The following remediation steps are recommended / required by July 14, 2023: Apply updates per vendor instructions.
CVE-2023-32434 is exploitable with local system access, requires user interaction. This vulnerability is considered to have a low attack complexity. It has an exploitability score of 1.8 out of four. The potential impact of an exploit of this vulnerability is considered to be very high.
Integer Overflow or Wraparound
The software performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. An integer overflow or wraparound occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may wrap to become a very small or negative number. While this may be intended behavior in circumstances that rely on wrapping, it can have security consequences if the wrap is unexpected. This is especially the case if the integer overflow can be triggered using user-supplied inputs. This becomes security-critical when the result is used to control looping, make a security decision, or determine the offset or size in behaviors such as memory allocation, copying, concatenation, etc.
