"Several security vulnerabilities were discovered in DOSBox, an
emulator for running old DOS programs.

CVE-2019-7165

A very long line inside a bat file would overflow the parsing buffer
which could be used by an attacker to execute arbitrary code.

CVE-2019-12594

Insufficient access controls inside DOSBox allowed attackers to access
resources on the host system and execute arbitrary code.

For Debian 8 'Jessie', these problems have been fixed in version
0.74-4+deb8u1.

We recommend that you upgrade your dosbox packages.

block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues.");
