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