    Package        : libxml2
    CVE ID         : CVE-2014-3660
    Debian Bug     : 762864 765722 765770
    
    Sogeti found a denial of service flaw in libxml2, a library providing
    support to read, modify and write XML and HTML files. A remote attacker
    could provide a specially crafted XML file that, when processed by an
    application using libxml2, would lead to excessive CPU consumption
    (denial of service) based on excessive entity substitutions, even if
    entity substitution was disabled, which is the parser default behavior.
    (CVE-2014-3660)
    
    In addition, this update addresses a misapplied chunk for a patch
    released in version 2.8.0+dfsg1-7+wheezy1 (#762864), and a memory leak
    regression (#765770) introduced in version 2.8.0+dfsg1-7+nmu3.
    
    For the stable distribution (wheezy), this problem has been fixed in
    version 2.8.0+dfsg1-7+wheezy2.
    
    For the unstable distribution (sid), this problem has been fixed in
    version 2.9.2+dfsg1-1.
    
    We recommend that you upgrade your libxml2 packages.
