Advisory:
========================

Updated memcached packages fix security vulnerability:

The try_read_command function in memcached.c in memcached before 1.4.39 allows
remote attackers to cause a denial of service (segmentation fault) via a request
to add/set a key, which makes a comparison between signed and unsigned int and
triggers a heap-based buffer over-read (CVE-2017-9951).

MGA5-32 on Dell Latitude D600
No installation issues.
Tried to follow test as per bug 12156, after installing php, but get
$ php memcac.php 
PHP Fatal error:  Class 'Memcached' not found in /home/tester5/Documenten/memcac.php on line 4
Apparently something still missing in this new setup, but that will have to wait until tomorrow.

Found out that I needed to install the package php-memcached.
Once this in place, the test as mentioned above runs OK:
$ php memcac.php 
my test data : SUCCESS

Whiteboard: MGA5TOO => MGA5TOO MGA5-32-OK

Trying M6/64

Installing from issued repos 'memcached-1.4.25-2.mga6.x86_64'.

UPDATEd to: memcached-1.4.39-1.mga6'
Using the quick test given in
 https://bugs.mageia.org/show_bug.cgi?id=12156#c8
which (comment 5) needs also 'php-memcached'.
Problem: wrong output
 $ php memcachedtest.php 
                         [blank line, the final \n I suppose]
 $

 For reference:
$ cat memcachedtest.php 
#!/bin/php
<?php

$m = new Memcached();
$m->addServer('127.0.0.1', 11211);
$m->set('test', 'my test data : SUCCESS');
echo $m->get('test') . "\n";
?>
 I added the final '?>' line, but with or without it, the result was the same.
Tried adding also memcached-devel-1.4.39-1.mga6.x86_64, which made no difference. Am I doing something silly?

CCing Samuel [test author] in case he can advise.

Continuing M6/64
Downgraded memcached to PREupdate version 1.4.25-2, and got the same test non-result as above; so it is at least not due to the update.

@ Lewis: Copy of my test #!/bin/php
<?php

$m = new Memcached();
$m->addServer('127.0.0.1', 11211);
$m->set('test', 'my test data : SUCCESS');
echo $m->get('test') . "\n";file that did OK:

Did you check the package php-memcached?

(In reply to Herman Viaene from comment #8)
> Did you check the package php-memcached?
Yes: php-memcached-2.2.0-2.mga6

I copied the script you gave above (which looked exactly the same as what I had); still no joy (here after the update):
memcached-1.4.39-1.mga6
 $ ./memcachedtest.php 

 $
Will ask around.

Installed and tested without issues.

System: Mageia 5, x86_64, Intel CPU.

This was not correct. It should have been (and was previously in c.6, and now):
 $ php memcachedtest.php 

 $
@PC_LX: Thank you for confirming Mageia 5 x64.

In my comment I forgot to mention that the memcached must be installed and running. If memcached is not running then the test script memcachedtest.php will output nothing.

I used the following commands to install, enable, start and check the status of the memcached service.
# urpmi memcached
# systemctl enable memcached@11211
# systemctl start memcached@11211
# systemctl status memcached@11211

Brilliant! That is all it was. It had not occured to me that a daemon was involved and might not be running; normally when daemons are installed, they are started.
