The following updates has been released for Debian 7 LTS

[DLA 519-1] icedove security update
[DLA 522-1] python2.7 security update

[DLA 519-1] icedove security update
Package : icedove
Version : 45.1.0-1~deb7u1
CVE ID : CVE-2016-2806

Multiple security issues have been found in Icedove, Debian's version of
the Mozilla Thunderbird mail client: Multiple memory safety errors may
lead to the execution of arbitrary code or denial of service.

Debian follows the extended support releases (ESR) of Thunderbird. Support
for the 38.x series has ended, so starting with this update we're now
following the 45.x releases.

For Debian 7 "Wheezy", these problems have been fixed in version
45.1.0-1~deb7u1.

We recommend that you upgrade your icedove packages.

[DLA 522-1] python2.7 security update
Package : python2.7
Version : 2.7.3-6+deb7u3
CVE ID : CVE-2016-0772 CVE-2016-5636 CVE-2016-5699

* CVE-2016-0772
A vulnerability in smtplib allowing MITM attacker to perform a
startTLS stripping attack. smtplib does not seem to raise an
exception when the remote end (smtp server) is capable of
negotiating starttls but fails to respond with 220 (ok) to an
explicit call of SMTP.starttls(). This may allow a malicious
MITM to perform a startTLS stripping attack if the client code
does not explicitly check the response code for startTLS.
* CVE-2016-5636
Issue #26171: Fix possible integer overflow and heap corruption
in zipimporter.get_data().
* CVE-2016-5699
Protocol injection can occur not only if an application sets a
header based on user-supplied values, but also if the application
ever tries to fetch a URL specified by an attacker (SSRF case) OR
if the application ever accesses any malicious web server
(redirection case).

For Debian 7 "Wheezy", these problems have been fixed in version
2.7.3-6+deb7u3.

We recommend that you upgrade your python2.7 packages.
