CVE-2011-3919: Juri Aedla discovered a heap-based buffer overflow that allows remote attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors.
CVE-2011-0216: An Off-by-one error have been discovered that allows remote attackers to execute arbitrary code or cause a denial of service.
CVE-2011-2821: A memory corruption (double free) bug has been identified in libxml2's XPath engine. Through it, it is possible for an attacker to cause a denial of service or possibly have unspecified other impact. This vulnerability does not affect the oldstable distribution (lenny).
CVE-2011-2834: Yang Dingning discovered a double free vulnerability related to XPath handling.
CVE-2011-3905: An out-of-bounds read vulnerability had been discovered, which allows remote attackers to cause a denial of service.
For the oldstable distribution (lenny), this problem has been fixed in version 2.6.32.dfsg-5+lenny5.
For the stable distribution (squeeze), this problem has been fixed in version 2.7.8.dfsg-2+squeeze2.
For the testing distribution (wheezy), this problem has been fixed in version 2.7.8.dfsg-7.
For the unstable distribution (sid), this problem has been fixed in version 2.7.8.dfsg-7.
We recommend that you upgrade your libxml2 packages.");
