Scientific Linux Security Update : pki-core on SL6.x i386/x86_64 (20130221)

Synopsis
The remote Scientific Linux host is missing one or more security updates.Description
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.
