CVE-2023-39615

libxml2: crafted xml can cause global buffer overflow

Published Aug 29, 2023 CVSS 3.1 · 6.5 Medium EPSS 1.1% KEV · Not listed
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.
