New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it is different from CVSS.

VPR Score: 6.7


The remote FreeBSD host is missing one or more security-related updates.


Rudolf Polzer reports :

a2ps builds a command line for file() containing an unescaped version of the file name, thus might call external programs described by the file name. Running a cronjob over a public writable directory a2ps-ing all files in it - or simply typing 'a2ps *.txt' in /tmp - is therefore dangerous.


Update the affected packages.
