Synopsis: Moderate: pki-core security, bug fix and enhancement
update
Issue Date: 2013-02-21
CVE Numbers: CVE-2012-4543

Note: The Certificate Authority component provided by this advisory
cannot be used as a standalone server. It is installed and operates as a part of
Identity Management (the IPA component) in Scientific Linux.

Multiple cross-site scripting flaws were discovered in Certificate
System. An attacker could use these flaws to perform a cross-site scripting (XSS)
attack against victims using Certificate System's web interface. (CVE-2012-4543)

This update also fixes the following bugs:

* Previously, due to incorrect conversion of large integers while
generating a new serial number, some of the most significant bits in the serial
number were truncated. Consequently, the serial number generated for certificates was
sometimes smaller than expected and this incorrect conversion in turn
led to a collision if a certificate with the smaller number already existed in the
database. This update removes the incorrect integer conversion so that no
serial numbers are truncated. As a result, the installation wizard
proceeds as expected.

* The certificate authority used a different profile for issuing the audit
certificate than it used for renewing it. The issuing profile was for two
years, and the renewal was for six months. They should both be for two
years. This update sets the default and constraint parameters in the
caSignedLogCert.cfg audit certificate renewal profile to two years.

This update also adds the following enhancements:

* IPA (Identity, Policy and Audit) now provides an improved way to determine
that PKI is up and ready to service requests. Checking the service
status was not sufficient. This update creates a mechanism for clients to determine
that the PKI subsystem is up using the getStatus() function to query the
cs.startup_state in CS.cfg.

* This update increases the default root CA validity period from eight
years to twenty years.
