FreeBSD : pcre -- stack buffer overflow (7033b42d-ef09-11e5-b766-14dae9d210b8)

critical Nessus Plugin ID 90050
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

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

Description

Philip Hazel reports :

PCRE does not validate that handling the (*ACCEPT) verb will occur within the bounds of the cworkspace stack buffer, leading to a stack buffer overflow.

Solution

Update the affected packages.
