Vulnerability Details

A security-sensitive bug was discovered goutils before version 1.1.1.

The functions RandomAlphaNumeric(int) and CryptoRandomAlphaNumeric(int) are not as random as they should be. Small values of int in the functions above will return a smaller subset of results than they should. For example, RandomAlphaNumeric(1) will always return a digit in the 0-9 range, while RandomAlphaNumeric(4) will return around ~7 million of the ~13M possible permutations.

This is considered a security release because programs that rely upon random generators for passwords are at an increased risk of brute force-style password guessing. There is also a higher probability of collision.

The problem was the result of a mistaken regular expression that only accepted random strings if they contained a digit from [0-9]. That restriction has been removed.
