(RHSA-2013:0856) Important: pki-tps security update

Red Hat Certificate System (RHCS) is an enterprise software system designed
to manage enterprise Public Key Infrastructure (PKI) deployments. The Token
Processing System (TPS) is a PKI subsystem that acts as a Registration
Authority (RA) for authenticating and processing enrollment requests, PIN
reset requests, and formatting requests from the Enterprise Security
Client.

A format string flaw was found in the TPS subsystem. An authenticated
Certificate System user could use this flaw to crash the Apache HTTP Server
child process, possibly interrupting the processing of other users’
requests, or possibly execute arbitrary code with pkiuser privileges.
(CVE-2013-1886)

A cross-site scripting flaw was discovered in the TPS subsystem. An
attacker could use this flaw to perform a cross-site scripting (XSS) attack
against victims using Certificate System’s web interface. (CVE-2013-1885)

All users of Red Hat Certificate System are advised to upgrade to this
updated package, which corrects these issues. After installing this update,
all Red Hat Certificate System subsystems must be restarted (“/etc/init.d
/[instance-name] restart”) for the update to take effect.
