The remote Amazon Linux AMI host is missing a security update.
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-2013-5607, CVE-2013-1741)
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.
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 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, CVE-2013-1620)
