The following updates and notifications has been publish for Debian GNU/Linux:

Debian GNU/Linux 7 Extended LTS:

DSA 4457-1: evolution security update

ELA-129-1 mysql-5.5 end of life notification

Upstream has ended the support for the MySQL 5.5 release series, and since no information is available which would allow backports of isolated security fixes, security support for MySQL in wheezy has to be ended as well.
Support will end on June 30th, 2019. Any serious flaws that are discovered before then will be backported if feasible.

Package : qemu
Debian Bug : 929067

Vincent Tondellier reported that the qemu update issued as DSA 4454-1
did not correctly backport the support to define the md-clear bit to
allow mitigation of the MDS vulnerabilities. Updated qemu packages are
now available to correct this issue.

For the stable distribution (stretch), this problem has been fixed in
version 1:2.8+dfsg-6+deb9u7.

We recommend that you upgrade your qemu packages.

Package : evolution
CVE ID : CVE-2018-15587
Debian Bug : 924616

Hanno Böck discovered that Evolution was vulnerable to OpenPGP
signatures being spoofed for arbitrary messages using a specially
crafted HTML email. This issue was mitigated by moving the security
bar with encryption and signature information above the message
headers.

For the stable distribution (stretch), this problem has been fixed in
version 3.22.6-1+deb9u2.

We recommend that you upgrade your evolution packages.
