Attention SL 5 MySQL users:

Upstream will not issue any more security advisories for the MySQL 5.0
packages (mysql-5.0.* and related packages).

In order to ensure your systems are fully up to date with security
errata, you must migrate to the newly provided MySQL 5.5 packages.

Future security advisories will be provided only for MySQL 5.5.

The only trusted way to upgrade from MySQL 5.0 to MySQL 5.5 is by using
MySQL 5.1 as an intermediate step. This is why the mysql51* Software
Collection packages are provided. Note that the MySQL 5.1 packages are
not supported and are provided only for the purposes of migrating to
MySQL 5.5. You should not use the mysql51* packages on any of your
production systems.

Because the mysql51 and mysql55 Software Collections do not conflict
with each other, or any mysql packages, users can install mysql51 and
mysql55 Software Collections together with mysql packages.

We have placed the relevant mysql packages within the Scientific Linux 5
security tree to facilitate this upgrade in advance of any actual
security errata. Giving you the time to test this migration should
result in you being better prepared for a time when you must perform it
to maintain your system security.

Specific instructions for this migration are provided by upstream at:
https://docs.redhat.com/en/documentation/Red_Hat_Enterprise_Linux/5/html/Deployment_Guide/ch-Migrating_from_MySQL_5.0_to_MySQL_5.5.html

Synopsis: Important: nss and nspr security, bug fix, and enhancement update
Advisory ID: SLSA-2013:1791-1
Issue Date: 2013-12-05
CVE Numbers: CVE-2013-1739
 CVE-2013-5605
 CVE-2013-5606
 CVE-2013-1741
 CVE-2013-5607
--

A flaw was found in the way NSS handled invalid handshake packets. A
remote attacker could use this flaw to cause a TLS/SSL client using NSS to
crash or, possibly, execute arbitrary code with the privileges of the user
running the application. (CVE-2013-5605)

It was found that the fix for CVE-2013-1620 released via SLSA-2013:1135
introduced a regression causing NSS to read uninitialized data when a
decryption failure occurred. A remote attacker could use this flaw to
cause a TLS/SSL server using NSS to crash. (CVE-2013-1739)

An integer overflow flaw was discovered in both NSS and NSPR's
implementation of certification parsing on 64-bit systems. A remote
attacker could use these flaws to cause an application using NSS or NSPR
to crash. (CVE-2013-1741, CVE-2013-5607)

It was discovered that NSS did not reject certificates with incompatible
key usage constraints when validating them while the verifyLog feature was
enabled. An application using the NSS certificate validation API could
accept an invalid certificate. (CVE-2013-5606)

In addition, the nss package has been upgraded to upstream version 3.15.3,
and the nspr package has been upgraded to upstream version 4.10.2. These
updates provide a number of bug fixes and enhancements over the previous
versions.

This update also fixes the following bug:

* The SLBA-2013:1318 update introduced a regression that prevented the use
of certificates that have an MD5 signature. This update fixes this
regression and certificates that have an MD5 signature are once again
supported. To prevent the use of certificates that have an MD5 signature,
set the "NSS_HASH_ALG_SUPPORT" environment variable to "-MD5".

After installing this update, applications using NSS or NSPR must be
restarted for this update to take effect.
