Medium: axis

Issue Overview: Apache Axis did not verify that the server hostname matched the domain name in the subject's Common Name CN or subjectAltName field in X.509 certificates. This could allow a man-in-the-middle attacker to spoof an SSL server if they had a certificate that was valid for any domain...

Medium: bind

Issue Overview: A flaw was found in the DNS64 implementation in BIND when using Response Policy Zones RPZ. If a remote attacker sent a specially-crafted query to a named server that is using RPZ rewrite rules, named could exit unexpectedly with an assertion failure. Note that DNS64 support is not...

Medium: dnsmasq

Issue Overview: It was discovered that dnsmasq, when used in combination with certain libvirtd configurations, could incorrectly process network packets from network interfaces that were intended to be prohibited. A remote, unauthenticated attacker could exploit this flaw to cause a denial of...

Medium: openssh

Issue Overview: Due to the way the pamsshagentauth PAM module was built, the glibc's error function was called rather than the intended error function in pamsshagentauth to report errors. As these two functions expect different arguments, it was possible for an attacker to cause an application...
