Description Paul Wouters 2012-04-25 15:58:54 UTC
crypt() may return NULL, so one should not directly attempt to strcmp() or strdup() its return value.

This can happen in various cases, for example when the host is running in FIPS mode and the hash algorithm specified in the salt , eg MD5 using $1$, is not allowed.

Attached patch fixes this,
