| Description: | Summary:
The remote host is missing an update for the 'openssl' package(s) announced via the ALAS-2013-171 advisory.
Vulnerability Insight:
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.
Affected Software/OS:
'openssl' package(s) on Amazon Linux.
Solution:
Please install the updated package(s).
CVSS Score:
5.0
