crypto weakness #293


Weakness Breakdown


This weakness involves creating non-standard or non-tested algorithms, using weak algorithms or applying cryptographic algorithms incorrectly. Algorithms that were once considered safe are commonly later found to be unsafe, as the algorithms were broken.

Warning code(s):

The crypt functions use a poor one-way hashing algorithm; since they only accept passwords of 8 characters or fewer and only a two-byte salt, they are excessively vulnerable to dictionary attacks given today's faster computing equipment.

The highlighted line of code below is the trigger point of this particular Fedora 24 crypto weakness.

 * wincapi.c: implementation of wincapi.h.

#include "putty.h"

#if !defined NO_SECURITY

#include "wincapi.h"

int got_crypt(void)
    static int attempted = FALSE;
    static int successful;
    static HMODULE crypt;

    if (!attempted) {
        attempted = TRUE;
        crypt = load_system32_dll("crypt32.dll");
        successful = crypt &&
            GET_WINDOWS_FUNCTION(crypt, CryptProtectMemory);
    return successful;
