Package        : dropbear
CVE ID         : CVE-2017-9078 CVE-2017-9079

Two vulnerabilities were found in Dropbear, a lightweight SSH2 server
and client:

CVE-2017-9078

    Mark Shepard discovered a double free in the TCP listener cleanup
    which could result in denial of service by an authenticated user if
    Dropbear is running with the "-a" option.

CVE-2017-9079

    Jann Horn discovered a local information leak in parsing the
    .authorized_keys file.

For the stable distribution (jessie), these problems have been fixed in
version 2014.65-1+deb8u2.

For the unstable distribution (sid), these problems will be fixed soon.

We recommend that you upgrade your dropbear packages.
