In Eclipse ThreadX NetX Duo before 6.4.0, if an attacker can control parameters of __portable_aligned_alloc() could cause an integer wrap-around and an allocation smaller than expected. This could cause subsequent heap buffer overflows.
The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow.
The 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.
