Descriptions
Xmlsoft Libxml2 v2.11.0 was discovered to contain an out-of-bounds read via the xmlSAX2StartElement() function at /libxml2/SAX2.c. This vulnerability allows attackers to cause a Denial of Service (DoS) via supplying a crafted XML file. NOTE: the vendor's position is that the product does not support the legacy SAX1 interface with custom callbacks; there is a crash even without crafted input.
A flaw was found in Libxml2, where it contains a global buffer overflow via the xmlSAX2StartElement() function at /libxml2/SAX2.c. This vulnerability allows attackers to cause a denial of service (DoS) by supplying a crafted XML file.
