Subject: Security ERRATA Important: nss and nspr on SL5.x i386/x86_64
Newsgroups: gmane.linux.scientific.errata
Date: Monday 9th December 2013 16:00:12 UTC (over 2 years ago)
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.
