FreeBSD php5-posix-5.2.6 has known vulnerabilities error – Stop in /usr/ports/sysutils/php5-posix.

Q. When I run make install clean for php5-extensions port, I'm dumped with the following error:

/usr/ports/sysutils/php5-posix
===> php5-posix-5.2.6 has known vulnerabilities:
=> php -- input validation error in posix_access function.
Reference: < http://www.FreeBSD.org/ports/portaudit/ee6fa2bd-406a-11dd-936a-0015af872849.html >
=> Please update your ports tree and try again.
*** Error code 1

Stop in /usr/ports/sysutils/php5-posix.
*** Error code 1

Stop in /usr/ports/lang/php5-extensions.
*** Error code 1

Stop in /usr/ports/lang/php5-extensions.

How do I fix this error?

A. Try upgrading your port tree by typing the following commands:
# portsnap fetch update
# portaudit -Fda
If you still see the error, temporarily disable error by adding following code to /etc/make.conf file:

# get around php5-posix error
.if !empty(.CURDIR:M*sysutils/php5-posix*)
DISABLE_VULNERABILITIES=yes
.endif

Save and close the file. Try to rebuild port again:
# cd /usr/ports/lang/php5-extensions
# make install clean

Another option is build /usr/ports/lang/php5-extensions port without looking at VULNERABILITIES:
# make -DDISABLE_VULNERABILITIES install

According to FreeBSD security team:

It should be noted that this vulnerability is not considered to be serious by the FreeBSD Security Team, since safe_mode and open_basedir are insecure by design and should not be relied upon.
