{"vuid":"VU#527736","idnumber":"527736","name":"mkpasswd uses weak random number generator","keywords":["expect","mkpasswd","RedHat","red hat","linux","Don Libes"],"overview":"Mkpasswd generates passwords that are insufficiently random.","clean_desc":"Mkpasswd is a password generation utility included with Red Hat Linux and possibly other Linux distributions. Mkpasswd generates passwords that are not sufficiently random, which may allow an attacker to predict passwords and consequently gain unauthorized access to other accounts on the system. This vulnerability occurs because mkpasswd uses the current process ID as the seed for the random number generator. Because of this, the number of passwords is limited to the size of the process table on the operating system.","impact":"An attacker may be able to predict passwords and consequently gain unauthorized access to other accounts on the system.","resolution":"Apply a patch from your vendor.","workarounds":"","sysaffected":"","thanks":"This vulnerability was reported by Shez <shez@molions.com>.","author":"This document was written by Ian A.
