CVE-2015-1819 [MEDIUM] libxml2 vulnerabilities
Title: libxml2 vulnerabilities
Summary: Several security issues were fixed in libxml2.
Florian Weimer discovered that libxml2 incorrectly handled certain XML
data. If a user or automated system were tricked into opening a specially
crafted document, an attacker could possibly cause resource consumption,
resulting in a denial of service. This issue only affected
Ubuntu 12.04 LTS, Ubuntu 14.04 LTS and Ubuntu 15.04. (CVE-2015-1819)
Michal Zalewski discovered that libxml2 incorrectly handled certain XML
data. If a user or automated system were tricked into opening a specially
crafted document, an attacker could possibly cause libxml2 to crash,
resulting in a denial of service. This issue only affected
Ubuntu 12.04 LTS, Ubuntu 14.04 LTS and Ubuntu 15.04. (CVE-2015-7941)

CVE-2015-7942 [MEDIUM] CWE-122 libxml2: heap-based buffer overflow in xmlParseConditionalSections()
libxml2: heap-based buffer overflow in xmlParseConditionalSections()
The xmlParseConditionalSections function in parser.c in libxml2 does not properly skip intermediary entities when it stops parsing invalid input, which allows context-dependent attackers to cause a denial of service (out-of-bounds read and crash) via crafted XML data, a different vulnerability than CVE-2015-7941.
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.
