b8ae4659-a0da-11e1-a294-bcaec565249clibxml2 -- An off-by-one out-of-bounds write by XPointer

Google chrome team reports:

An off-by-one out-of-bounds write flaw was found in the way libxml, a library for providing XML and HTML support, evaluated certain XPointer parts (XPointer is used by libxml to include only the part from the returned XML document, that can be accessed using the XPath expression given with the XPointer). A remote attacker could provide a specially-crafted XML file, which once opened in an application, linked against libxml, would lead to that application crash, or, potentially arbitrary code execution with the privileges of the user running the application.

Note: The flaw to be exploited requires the particular application, linked against libxml, to use the XPointer evaluation functionality.

0642b064-56c4-11e4-8b87-bcaec565249clibxml2 -- Denial of service

RedHat reports:

A denial of service flaw was found in libxml2, a library providing support to read, modify and write XML and HTML files. A remote attacker could provide a specially crafted XML file that, when processed by an application using libxml2, would lead to excessive CPU consumption (denial of service) based on excessive entity substitutions, even if entity substitution was disabled, which is the parser default behavior.

9c7177ff-1fe1-11e5-9a01-bcaec565249clibxml2 -- Enforce the reader to run in constant memory

Daniel Veilland reports:

Enforce the reader to run in constant memory. One of the operation on the reader could resolve entities leading to the classic expansion issue. Make sure the buffer used for xmlreader operation is bounded. Introduce a new allocation type for the buffers for this effect.

efdd0edc-da3d-11e3-9ecb-2c4138874f7dlibxml2 -- entity substitution DoS

Stefan Cornelius reports:

It was discovered that libxml2, a library providing support to read, modify and write XML files, incorrectly performs entity substitution in the doctype prolog, even if the application using libxml2 disabled any entity substitution. A remote attacker could provide a specially-crafted XML file that, when processed, would lead to the exhaustion of CPU and memory resources or file descriptors.

This issue was discovered by Daniel Berrange of Red Hat.

Integer overflow in xpath.c, allows context-dependent attackers to to cause a denial of service (crash) and possibly execute arbitrary code via a crafted XML file that triggers a heap-based buffer overflow when adding a new namespace node, related to handling of XPath expressions.
