Comment: This advisory references vulnerabilities in products which run on

Package        : leptonlib
Version        : 1.69-3.1+deb7u1
CVE ID         : CVE-2018-3836
Debian Bug     : 889759


Talosintelligence discovered a command injection vulnerability in the
gplotMakeOutput function of leptonlib. A specially crafted gplot
rootname argument can cause a command injection resulting in arbitrary
code execution. An attacker can provide a malicious path as input to an
application that passes attacker data to this function to trigger this
vulnerability.

For Debian 7 "Wheezy", these problems have been fixed in version
1.69-3.1+deb7u1.

We recommend that you upgrade your leptonlib packages.
