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: 3.6

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

A flaw was found in curl before version 7.51.0. The way curl handles cookies permits other threads to trigger a use-after-free leading to information disclosure. (CVE-2016-8623)

Impact

A use-after-free can occur with shared cookies, allowing a user or processunauthorized access to view or replace cookies sent by cURL. On the BIG-IP system, access to the cURL utility is restricted to locally authenticated users.

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution K84940705.
