ntpq_stripquotes()
returns incorrect value (Info) ntpq
, uses the function ntpq_stripquotes()
to remove quotes and escape characters from a given string. According to the documentation, the function is supposed to return the number of copied bytes but due to incorrect pointer usage this value is always zero. Although the return value of this function is never used in the code, this flaw could lead to a vulnerability in the future. Since relying on wrong return values when performing memory operations is a dangerous practice, it is recommended to return the correct value in accordance with the documentation pertinent to the code.
