Package        : openssh
CVE ID         : CVE-2015-8325

Shayan Sadigh discovered a vulnerability in OpenSSH: If PAM support is
enabled and the sshd PAM configuration is configured to read user-
specified environment variables and the "UseLogin" option is enabled, a
local user may escalate her privileges to root.

In Debian "UseLogin" is not enabled by default.

For the oldstable distribution (wheezy), this problem has been fixed
in version 6.0p1-4+deb7u4.

For the stable distribution (jessie), this problem has been fixed in
version 6.7p1-5+deb8u2.

For the unstable distribution (sid), this problem has been fixed in
version 1:7.2p2-3.

We recommend that you upgrade your openssh packages.
