"Todd Miller's sudo version 1.8.20p1 and earlier is vulnerable to an
input validation (embedded newlines) in the get_process_ttyname()
function resulting in information disclosure and command execution.

The previous announcement (DLA-970-1) was about a similar security
issue (CVE-2017-1000367) which wasn't completely fixed.

For Debian 7 'Wheezy', these problems have been fixed in version
1.8.5p2-1+nmu3+deb7u4.

We recommend that you upgrade your sudo packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues.");
