Scientific Linux Security Update : nss and nspr on SL5.x i386/x86_64 (20131205)

high Nessus Plugin ID 71306

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

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.

Solution

Update the affected packages.
