TITLE:
Red Hat Certificate Server Information Disclosure and Security Bypass

SECUNIA ADVISORY ID:
SA33693

VERIFY ADVISORY:
http://secunia.com/advisories/33693/

CRITICAL:
Less critical

IMPACT:
Security Bypass, Exposure of sensitive information

WHERE:
Local system

SOFTWARE:
Red Hat Directory Server 7.x
http://secunia.com/advisories/product/7016/

DESCRIPTION:
Red Hat has acknowledged some security issues in Red Hat Certificate
Server, which can be exploited by malicious, local users to bypass
certain security restrictions and to disclose potentially sensitive
information.

1) A security issue is caused due to insecure default access
permissions on certain configuration files (e.g. password.conf),
which can be exploited to disclose potentially sensitive
information.

2) A security issue is caused due to the Red Hat Certificate System
storing passwords in plaintext in various debug log files with
insecure permissions, which can be exploited to disclose passwords.

3) A security issue is caused due to the Token Processing System
(TPS) not properly verifying the challenge response when enrolling a
new security token. This can be exploited to perform a token
enrollment using a software-generated key instead of the key stored
in the hardware token. 

Successful exploitation requires the privileges to perform new token
enrollments and a blank token known to the TPS component.

SOLUTION:
Updated packages are available via Red Hat Network.
