Synopsis: Important: nss, nspr, and nss-util security update
Advisory ID: SLSA-2013:1829-1
Issue Date: 2013-12-12
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)

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