A xawtv security update has been released for Debian GNU/Linux 8 LTS to address an issue where arbitrary files can be open.

DLA 2246-1: xawtv security update

Package : xawtv
Version : 3.103-3+deb8u1
CVE ID : CVE-2020-13696
Debian Bug : 962221

An issue was discovered in LinuxTV xawtv before 3.107. The function
dev_open() in v4l-conf.c does not perform sufficient checks to
prevent an unprivileged caller of the program from opening unintended
filesystem paths. This allows a local attacker with access to the
v4l-conf setuid-root program to test for the existence of arbitrary
files and to trigger an open on arbitrary files with mode O_RDWR.
To achieve this, relative path components need to be added to the
device path, as demonstrated by a
v4l-conf -c /dev/../root/.bash_history command.

For Debian 8 "Jessie", this problem has been fixed in version
3.103-3+deb8u1.

We recommend that you upgrade your xawtv packages.
