libxslt: Heap Use-After-Free in libxslt caused by atype corruption in xmlAttrPtr
ecosystem: redhat:6, redhat:7, redhat:8, redhat:9, redhat:10A 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.
