Package : libxml2
Type : multiple issues

A memory leak was found in the xmlSchemaValidateStream function of
libxml2. Applications that use this library may be vulnerable to memory
not being freed leading to a denial of service.

infinite loop in a certain end-of-file situation.
GNOME project libxml2 <= 2.9.10 has a global buffer over-read
