Category:	Debian Local Security Checks
Title:	Debian Security Advisory DSA 2894-1 (openssh - security update)
Summary:	Two vulnerabilities were discovered in OpenSSH, an implementation of the;SSH protocol suite. The Common Vulnerabilities and Exposures project;identifies the following problems:;;CVE-2014-2532;Jann Horn discovered that OpenSSH incorrectly handled wildcards in;AcceptEnv lines. A remote attacker could use this issue to trick;OpenSSH into accepting any environment variable that contains the;characters before the wildcard character.;;CVE-2014-2653;Matthew Vernon reported that if a SSH server offers a;HostCertificate that the ssh client doesn't accept, then the client;doesn't check the DNS for SSHFP records. As a consequence a;malicious server can disable SSHFP-checking by presenting a;certificate.;;Note that a host verification prompt is still displayed before;connecting.
