FreeBSD : guile2 -- multiple vulnerabilities (b4ecf774-eb01-11e6-9ac1-a4badb2f4699)

critical Nessus Plugin ID 96994

Language:

Synopsis

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

Description

Ludovic Courtes reports :

The REPL server is vulnerable to the HTTP inter-protocol attack

The 'mkdir' procedure of GNU Guile, an implementation of the Scheme programming language, temporarily changed the process' umask to zero. During that time window, in a multithreaded application, other threads could end up creating files with insecure permissions.

Solution

Update the affected package.
