DESCRIPTION:
Some vulnerabilities have been reported in Red Hat Certificate
System, which can be exploited by malicious users to bypass certain
security restrictions and by malicious people to conduct cross-site
scripting attacks.

1) An error due to the certificate authority not properly checking
certificate revocation requests via web interface can be exploited to
revoke the Certificate Authority (CA) certificate.

Successful exploitation of this vulnerability requires permissions to
revoke end entity certificates.

2) Certain unspecified input is not properly sanitised in System
Agent and End Entity pages before being returned to the user. This
can be exploited to execute arbitrary HTML and script code in a
user's browser session in context of Certificate System's web
interface.

SOLUTION:
Updated packages are available via Red Hat Network.
