Gmane
From: Pat Riehecky <riehecky-13hema8v3vg <at> public.gmane.org>
Subject: Security ERRATA Moderate: nss, nss-util, nss-softokn, and nspr on SL6.x i386/x86_64
Newsgroups: gmane.linux.scientific.errata
Date: Thursday 8th August 2013 14:25:49 UTC (over 3 years ago)
Synopsis:          Moderate: nss, nss-util, nss-softokn, and nspr security
update
Advisory ID:       SLSA-2013:1144-1
Issue Date:        2013-08-07
CVE Numbers:       CVE-2013-1620
                   CVE-2013-0791
--

It was discovered that NSS leaked timing information when decrypting
TLS/SSL and DTLS protocol encrypted records when CBC-mode cipher suites
were used. A remote attacker could possibly use this flaw to retrieve
plain text from the encrypted packets by using a TLS/SSL or DTLS server as
a padding oracle. (CVE-2013-1620)

An out-of-bounds memory read flaw was found in the way NSS decoded certain
certificates. If an application using NSS decoded a malformed certificate,
it could cause the application to crash. (CVE-2013-0791)

This update also fixes the following bugs:

* The SLBA-2013:0445 update (which upgraded NSS to version 3.14) prevented
the use of certificates that have an MD5 signature. This caused problems
in certain environments. With this update, certificates that have an MD5
signature are once again allowed. To prevent the use of certificates that
have an MD5 signature, set the "NSS_HASH_ALG_SUPPORT" environment variable
to "-MD5".

* Previously, the sechash.h header file was missing, preventing certain
source RPMs (such as firefox and xulrunner) from building.

* A memory leak in the nssutil_ReadSecmodDB() function has been fixed.

In addition, the nss package has been upgraded to upstream version 3.14.3,
the nss-util package has been upgraded to upstream version 3.14.3, the
nss-softokn package has been upgraded to upstream version 3.14.3, and the
nspr package has been upgraded to upstream version 4.9.5. These updates
provide a number of bug fixes and enhancements over the previous versions.

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