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's different from CVSS.

VPR Score: 6.7

Synopsis

The remote FreeBSD host is missing a security-related update.

Description

SO-AND-SO reports :

A memory corruption issue was found in Artifex Ghostscript 9.50 and 9.52. Use of a non-standard PostScript operator can allow overriding of file access controls. The 'rsearch' calculation for the 'post' size resulted in a size that was too large, and could underflow to max uint32_t. This was fixed in commit 5d499272b95a6b890a1397e11d20937de000d31b.

Solution

Update the affected package.
