CVE-2024-34391
libxmljs is vulnerable to a type confusion vulnerability when parsing a specially crafted XML while invoking a function on the result of attrs() that was called on a parsed node.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.10%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
libxmljs is vulnerable to a type confusion vulnerability when parsing a specially crafted XML while invoking a function on the result of attrs() that was called on a parsed node. This vulnerability might lead to denial of service (on both 32-bit systems and 64-bit systems), data leak, infinite loop and remote code execution (on 32-bit systems with the XML_PARSE_HUGE flag enabled).
