Fixed in Cauldron by Oden.

Version: Cauldron => 2
Whiteboard: MGA2TOO => (none)

Fix added in r334303 (mga2, updates_testing, apache-mod_security-2.6.3-3.3.mga2). Test with the PoC from http://seclists.org/fulldisclosure/2012/Oct/113

Thanks Oden!  I'm guessing crs doesn't need an update for 2.

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

Updated apache-mod_security packages fix security vulnerability:

ModSecurity before 2.7.0 is vulnerable to multipart/invalid part ruleset
bypass (CVE-2012-4528).

I'm not having any luck with the PoC, can you give any insight into how to use it please.

Tried with curl (-d and -H) and using 'postit' firefox extension.

I put the PoC data into a file called 8292

Claire, POST is  a command.
$ rpm -q -f /usr/bin/POST
perl-libwww-perl-6.40.0-1.mga2

Even with that though, I'm not having much luck with the POC yet either.
Still looking into it.

[dave@i2v ~]$ POST /wut.php HTTP/1.1
Please enter content (application/x-www-form-urlencoded) to be POSTed:

Content-Disposition: form-data; name="yyy"; filename="z"

1 UNION SELECT 1,2,3,4,5,6,7,8,9,10--

--A--

I pressed enter, then ctrl+d after pasting in the content.

Without a working POC, I'd rather just test that the updated package
works.  We don't have any packages that require apache-mod_security,
and as this is a security update, just testing that the updated module
loads with ...
# httpd -M 2>/dev/null |grep security
 security_module (shared)

Testing complete on Mageia 2 i586 and x86-64.

Could someone from the sysadmin team push the srpm
apache-mod_security-2.6.3-3.3.mga2.src.rpm
from Mageia 2 Core Updates Testing to Core Updates.

Advisory: Updated apache-mod_security packages fix security vulnerability:
