Debian Security Advisory DSA-2659-1 email@example.com http://www.debian.org/security/ Salvatore Bonaccorso April 09, 2013 http://www.debian.org/security/faq
Package : libapache-mod-security Vulnerability : XML external entity processing vulnerability Problem type : remote Debian-specific: no CVE ID : CVE-2013-1915 Debian Bug : 704625
Timur Yunusov and Alexey Osipov from Positive Technologies discovered that the XML files parser of ModSecurity, an Apache module whose purpose is to tighten the Web application security, is vulnerable to XML external entities attacks. A specially-crafted XML file provided by a remote attacker, could lead to local file disclosure or excessive resources (CPU, memory) consumption when processed.
This update introduces a SecXmlExternalEntity option which is 'Off' by default. This will disable the ability of libxml2 to load external entities.
For the stable distribution (squeeze), this problem has been fixed in version 2.5.12-1+squeeze2.
For the testing distribution (wheezy), this problem has been fixed in version 2.6.6-6 of the modsecurity-apache package.
For the unstable distribution (sid), this problem has been fixed in version 2.6.6-6 of the modsecurity-package package.
We recommend that you upgrade your libapache-mod-security packages.
