The remote Oracle Linux host is missing one or more security updates.
From Red Hat Security Advisory 2013:1791 :
Updated nss and nspr packages that fix multiple security issues,
several bugs, and add various enhancements are now available for Red
Hat Enterprise Linux 5.
The Red Hat Security Response Team has rated this update as having
important security impact. Common Vulnerability Scoring System (CVSS)
base scores, which give detailed severity ratings, are available for
each vulnerability from the CVE links in the References section.
Network Security Services (NSS) is a set of libraries designed to
support the cross-platform development of security-enabled client and
server applications. Netscape Portable Runtime (NSPR) provides
platform independence for non-GUI operating system facilities.
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
RHSA-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
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.
Red Hat would like to thank the Mozilla project for reporting
CVE-2013-1741, CVE-2013-5606, and CVE-2013-5607. Upstream acknowledges
Tavis Ormandy as the original reporter of CVE-2013-1741, Camilo Viecco
as the original reporter of CVE-2013-5606, and Pascal Cuoq, Kamil
Dudka, and Wan-Teh Chang as the original reporters of CVE-2013-5607.
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. (BZ#1033478, BZ#1020520)
This update also fixes the following bug :
* The RHBA-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
Users of NSS and NSPR are advised to upgrade to these updated
packages, which fix these issues and add these enhancements. After
installing this update, applications using NSS or NSPR must be
restarted for this update to take effect.
