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.
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.
