Bugzilla Bug 262302

From Secunia:

Two vulnerabilities have been reported in ModSecurity, which can be
exploited by malicious people to cause a DoS (Denial of Service).

1) An error in the PDF XSS protection implementation can be exploited
to cause a crash via a specially crafted HTTP request.

Successful exploitation requires that PDF XSS protection is enabled
(disabled by default).

2) An error when parsing multipart requests can be exploited to cause
a crash via multipart content with a missing part header name.

chtekk, apache guys: Please bump to 2.5.9.
(http://sourceforge.net/project/shownotes.php?release_id=667542)

Created an attachment (id=188238) [details]
ebuild for version 2.5.9

This is my quick and dirty approach for an 2.5.9 ebuild that built fine for me
(x86 arch). This is basically the 2.5.7 ebuild with "econf
--with-apxs="${APXS}" \" commented out.

I've added a 2.5.9 ebuild with the proper fix for the broken autotools (also
reported upstream).

Arches, please test and mark stable:
=www-apache/mod_security-2.5.9
Target keywords : "amd64 ppc sparc x86"

amd64/x86 stable

ppc done

sparc stable

ebuild doesn't work for me:

bug 272401, already resolved. (Broken LDFLAGS on the user's machine)

CVE-2009-1902 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-1902):
  The multipart processor in ModSecurity before 2.5.9 allows remote
  attackers to cause a denial of service (crash) via a multipart form
  datapost request with a missing part header name, which triggers a
  NULL pointer dereference.

CVE-2009-1903 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-1903):
  The PDF XSS protection feature in ModSecurity before 2.5.8 allows
  remote attackers to cause a denial of service (Apache httpd crash)
  via a request for a PDF file that does not use the GET method.

Yes, too.

Request was filed.
