CVE-2014-9721

CVE-2014-9721 affects libzmq (ZeroMQ core library). Affected versions are libzmq before 4.0.6 and 4.1.x before 4.1.1, where a remote attacker can trigger downgrade attacks to bypass the ZMTP v3 protocol security by sending a ZMTP v2 or earlier header. The issue is due to improper handling of olde...

CVE-2015-4000

The TLS protocol 1.2 and earlier, when a DHEEXPORT ciphersuite is enabled on a server but not on a client, does not properly convey a DHEEXPORT choice, which allows man-in-the-middle attackers to conduct cipher-downgrade attacks by rewriting a ClientHello with DHE replaced by DHEEXPORT and then...

Amazon Linux AMI : docker (ALAS-2015-522)

The file-descriptor passed by libcontainer to the pid-1 process of a container has been found to be opened prior to performing the chroot, allowing insecure open and symlink traversal. This allows malicious container images to trigger a local privilege escalation. CVE-2015-3627 Libcontainer versi...

New MySQL Bug Can Strip SSL Protection From Connections

Researchers have identified a serious vulnerability in some versions of Oracle’s MySQL database product that allows an attacker to strip SSL/TLS connections of their security wrapping transparently. The vulnerability is the result of the way that an option in MySQL handles requests for secure...

CVE-2015-0282

GnuTLS before 3.1.0 does not verify that the RSA PKCS#1 signature algorithm matches the signature algorithm in the certificate, enabling remote downgrade attacks via unspecified vectors. Impact is downgrade/traffic manipulation risk with affected deployments. The CVE entry explicitly targets GnuTLS...
