There is an integer overflow vulnerability in LDAP client of some Huawei products. Due to insufficient input validation, a remote attacker could exploit this vulnerability by sending malformed packets to the target devices. Successful exploit could cause the affected system crash.
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.
