The following two security updates has been released for Debian GNU/Linux 7 LTS:

DLA 1353-1: wireshark security update
DLA 1354-1: opencv security update

DLA 1353-1: wireshark security update

Package : wireshark
Version : 1.12.1+g01b65bf-4+deb8u6~deb7u10
CVE ID : CVE-2018-7322 CVE-2018-7323 CVE-2018-7324 CVE-2018-7332

CVE-2018-7417 CVE-2018-7418 CVE-2018-7419 CVE-2018-7420


It was discovered that wireshark, a network protocol analyzer, contained
several vulnerabilities that could result in infinite loops in different
dissectors. Other issues are related to crash in dissectors that are
caused by special crafted and malformed packets.


For Debian 7 "Wheezy", these problems have been fixed in version
1.12.1+g01b65bf-4+deb8u6~deb7u10.

We recommend that you upgrade your wireshark packages.
