A denial of service flaw was found in libxml2. A remote attacker could provide a specially crafted XML or HTML file that, when processed by an application using libxml2, would cause that application to leak potentially sensitive information.(CVE-2015-8241)
A denial of service flaw was found in libxml2. A remote attacker could provide a specially crafted XML or HTML file that, when processed by an application using libxml2, would cause that application to use an excessive amount of CPU.(CVE-2015-5312)
A heap-based buffer overflow flaw was found in the way libxml2 parsed certain crafted XML input. A remote attacker could provide a specially crafted XML file that, when opened in an application linked against libxml2, would cause the application to crash causing a denial of service.(CVE-2015-7942)
It was discovered that libxml2 could access out-of-bounds memory when parsing unclosed HTML comments. A remote attacker could provide a specially crafted XML file that, when processed by an application linked against libxml2, could cause the application to disclose heap memory contents.(CVE-2015-8710)
