  - Off-by-one error in libxml in Apple Safari before 5.0.6
    allows remote attackers to execute arbitrary code or
    cause a denial of service (heap-based buffer overflow
    and application crash) via a crafted web site.
    (CVE-2011-0216)

  - Double free vulnerability in libxml2, as used in Google
    Chrome before 13.0.782.215, allows remote attackers to
    cause a denial of service or possibly have unspecified
    other impact via a crafted XPath expression.
    (CVE-2011-2821)

  - Double free vulnerability in libxml2, as used in Google
    Chrome before 14.0.835.163, allows remote attackers to
    cause a denial of service or possibly have unspecified
    other impact via vectors related to XPath handling.
    (CVE-2011-2834)

  - Off-by-one error in libxml2, as used in Google Chrome
    before 19.0.1084.46 and other products, allows remote
    attackers to cause a denial of service (out-of-bounds
    write) or possibly have unspecified other impact via
    unknown vectors. (CVE-2011-3102)

  - libxml2, as used in Google Chrome before 16.0.912.63,
    allows remote attackers to cause a denial of service
    (out-of-bounds read) via unspecified vectors.
    (CVE-2011-3905)

  - Heap-based buffer overflow in libxml2, as used in Google
    Chrome before 16.0.912.75, allows remote attackers to
    cause a denial of service or possibly have unspecified
    other impact via unknown vectors. (CVE-2011-3919)

  - libxml2 before 2.8.0 computes hash values without
    restricting the ability to trigger hash collisions
    predictably, which allows context-dependent attackers to
    cause a denial of service (CPU consumption) via crafted
    XML data. (CVE-2012-0841)"
