Description

When RPC is enabled in Wind River VxWorks 6.9 prior to 6.9.1, a specially crafted RPC request can trigger an integer overflow leading to an out-of-bounds memory copy. It may allow remote attackers to cause a denial of service (crash) or possibly execute arbitrary code.

• 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.
