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: 5.9

Synopsis

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

Description

The Asterisk project reports :

No size checking is done when setting the user field for Party B on a CDR. Thus, it is possible for someone to use an arbitrarily large string and write past the end of the user field storage buffer. The earlier AST-2017-001 advisory for the CDR user field overflow was for the Party A buffer.

Solution

Update the affected package.
