CVE-2025-7425 Details
Description
A flaw was found in libxslt where the attribute type, atype, flags are modified in a way that corrupts internal memory management. When XSLT functions, such as the key() process, result in tree fragments, this corruption prevents the proper cleanup of ID attributes. As a result, the system may access freed memory, causing crashes or enabling attackers to trigger heap corruption.
A heap use-after-free vulnerability has been identified in libxslt, caused by unsafe manipulation of the atype field in attribute nodes. This flaw arises when the xsltSetSourceNodeFlags() function adds extra flag bits to the atype field of xmlAttrPtr, which libxml2 later uses to determine if an attribute is an XML ID. The corruption prevents proper cleanup of ID attributes during memory deallocation, leading to dangling pointers. Exploitation is possible through crafted XSLT that uses the key() function, resulting in memory access violations that can cause crashes or heap corruption.
Users can apply the patch provided by Apple's fork of libxml2, which addresses the atype corruption without breaking ABI compatibility. This patched version of libxml2 can be used in conjunction with the fixed version of libxslt to eliminate the vulnerability.
