TITLE:
Red Hat update for yum-rhn-plugin

SECUNIA ADVISORY ID:
SA31472

VERIFY ADVISORY:
http://secunia.com/advisories/31472/

CRITICAL:
Less critical

IMPACT:
Spoofing

WHERE:
>From remote

OPERATING SYSTEM:
Red Hat Enterprise Linux (v. 5 server)
http://secunia.com/product/13652/
Red Hat Enterprise Linux Desktop (v. 5 client)
http://secunia.com/product/13653/

DESCRIPTION:
Red Hat has issued an update for yum-rhn-plugin. This fixes a
security issue, which can be exploited by malicious people to conduct
spoofing attacks.

The problem is that the certificate presented by a Red Hat Network
server is not always verified. This can be exploited to spoof valid
servers via a man-in-the-middle attack and provide malicious
repository metadata.

Successful exploitation allows the blocking of security updates.

SOLUTION:
Updated packages are available via Red Hat Network.
