Description

A vulnerability exists in the proxy packet processing logic of the affected component where it improperly processes malformed or truncated input. An unauthenticated remote attacker could exploit this vulnerability by providing specially crafted input that triggers an integer overflow. Successful exploitation could result in a buffer overflow, potentially leading to remote code execution or denial-of-service.

• CWE-190Integer Overflow or WraparoundThe product 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 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 become a very small or negative number.
