Details

It was discovered that libxml2 contained an off by one error. If a user or
application linked against libxml2 were tricked into opening a specially
crafted XML file, an attacker could cause the application to crash or
possibly execute arbitrary code with the privileges of the user invoking
the program. (CVE-2011-0216)

It was discovered that libxml2 is vulnerable to double-free conditions
when parsing certain XML documents. This could allow a remote attacker to
cause a denial of service. (CVE-2011-2821, CVE-2011-2834)

It was discovered that libxml2 did not properly detect end of file when
parsing certain XML documents. An attacker could exploit this to crash
applications linked against libxml2. (CVE-2011-3905)

It was discovered that libxml2 did not properly decode entity references
with long names. If a user or application linked against libxml2 were
tricked into opening a specially crafted XML file, an attacker could cause
the application to crash or possibly execute arbitrary code with the
privileges of the user invoking the program. (CVE-2011-3919)
