Security Advisory mod_ssl security update for Stronghold

Advisory: RHSA-2003:301-06
Type: Security Advisory
Severity: Moderate
Issued on: 2003-10-15
Last updated on: 2003-10-15
Affected Products: Red Hat Stronghold for Enterprise Linux
CVEs ( CVE-2003-0192


An updated mod_ssl package is now available for Stronghold 4 on Red Hat
Enterprise Linux that closes a security issue in certain rare configurations.

Stronghold 4 contains a number of open source technologies, including the
mod_ssl module (which provides SSL/TLS support for Apache).

Ben Laurie found a bug in the optional renegotiation code in mod_ssl
that can cause cipher suite restrictions to be ignored. This is triggered
if optional renegotiation is used (SSLOptions +OptRenegotiate) along with
verification of client certificates and a change to the cipher suite over
the renegotiation. The Common Vulnerabilities and Exposures project
( has assigned the name CAN-2003-0192 to this issue.

Users of Stronghold 4 on Red Hat Enterprise Linux may update to
this erratum package, which contains a backported security fix and is not
vulnerable to this issue.


Before applying this update, make sure all previously released errata
relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which are
not installed but included in the list will not be updated. Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
desired RPMs.

Please note that this update is also available via Red Hat Network. Many
people find this an easier way to apply updates. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:


This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.

If up2date fails to connect to Red Hat Network due to SSL Certificate
Errors, you need to install a version of the up2date client with an updated
certificate. The latest version of up2date is available from the Red Hat
FTP site and may also be downloaded directly from the RHN website:
