A flaw was found in libxslt where the attribute type, atype, flags are modified in a way that corrupts internal memory management.

As a result, the system may access freed memory, causing crashes or enabling attackers to trigger heap corruption.

xsltGetInheritedNsList in libxslt before 1.1.43 has a use-after-free issue related to exclusion of result prefixes.
