MEDIUM

Libxml2 2.11.0 - Denial of Service via xmlSAX2StartElement Out-of-Bounds Read

Title source: llm
STIX 2.1

Description

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.
