It was discovered that libxml2 incorrectly handled certain malformed documents. If a user or automated system were tricked into opening a specially crafted document, an attacker could cause libxml2 to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2016-1762, CVE-2016-1834)

Mateusz Jurczyk discovered that libxml2 incorrectly handled certain malformed documents. If a user or automated system were tricked into opening a specially crafted document, an attacker could cause libxml2 to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2016-1833, CVE-2016-1838, CVE-2016-1839)

Wei Lei and Liu Yang discovered that libxml2 incorrectly handled certain malformed documents. If a user or automated system were tricked into opening a specially crafted document, an attacker could cause libxml2 to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2016-1835, CVE-2016-1837)

Wei Lei and Liu Yang discovered that libxml2 incorrectly handled certain malformed documents. If a user or automated system were tricked into opening a specially crafted document, an attacker could cause libxml2 to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only applied to Ubuntu 14.04 LTS, Ubuntu 15.10 and Ubuntu 16.04 LTS. (CVE-2016-1836)

Kostya Serebryany discovered that libxml2 incorrectly handled certain malformed documents. If a user or automated system were tricked into opening a specially crafted document, an attacker could cause libxml2 to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2016-1840)
