Description:
A weakness has been reported in Openwall crypt_blowfish, which potentially can be exploited by malicious, local users to bypass certain security restrictions.
The weakness is caused due to signedness errors in crypt_gensalt.c. This increases the probability that certain extended-DES-based and MD5-based password hashes are generated using the same salt.
Successful exploitation allows the hashes to be tested against candidate passwords at a faster effective rate but requires access to the password file.
The weakness has been reported in version 0.4.7 and prior.
