The remote Amazon Linux AMI host is missing a security update.
It was discovered that OpenSSL leaked timing information when
decrypting TLS/SSL and DTLS protocol encrypted records when CBC-mode
cipher suites were used. A remote attacker could possibly use this
flaw to retrieve plain text from the encrypted packets by using a
TLS/SSL or DTLS server as a padding oracle. (CVE-2013-0169)
A NULL pointer dereference flaw was found in the OCSP response
verification in OpenSSL. A malicious OCSP server could use this flaw
to crash applications performing OCSP verification by sending a
specially crafted response. (CVE-2013-0166)
It was discovered that the TLS/SSL protocol could leak information
about plain text when optional compression was used. An attacker able
to control part of the plain text sent over an encrypted TLS/SSL
connection could possibly use this flaw to recover other portions of
the plain text. (CVE-2012-4929)
Note: This update disables zlib compression, which was previously
enabled in OpenSSL by default. Applications using OpenSSL now need to
explicitly enable zlib compression to use it.
