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: 1.4

Synopsis

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

Description

The cURL project reports :

There were two bugs in curl's parser for the command line option
--write-out (or -w for short) that would skip the end of string zero byte if the string ended in a % (percent) or \ (backslash), and it would read beyond that buffer in the heap memory and it could then potentially output pieces of that memory to the terminal or the target file etc..

This flaw only exists in the command line tool.

We are not aware of any exploit of this flaw.

Solution

Update the affected package.
