Debian Security Advisory DSA-2894-1 [email protected]
http://www.debian.org/security/ Salvatore Bonaccorso
April 05, 2014 http://www.debian.org/security/faq
Package : openssh
CVE ID : CVE-2014-2532 CVE-2014-2653
Debian Bug : 742513
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.
For the oldstable distribution (squeeze), these problems have been fixed in
version 1:5.5p1-6+squeeze5.
For the stable distribution (wheezy), these problems have been fixed in
version 1:6.0p1-4+deb7u1.
For the unstable distribution (sid), these problems have been fixed in
version 1:6.6p1-1.
We recommend that you upgrade your openssh packages.
