    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.
