Remediation
Red Hat statement
This issue does not affect the libxml library shipped with Red Hat Enterprise Linux because the affected code xmlMemoryStrdup() is a debug-only function that should never be called in production builds. The only exception is xmllint when invoked with --maxmem. The same issue applies to the other two affected functions namely xmlMallocLoc and xmlReallocLoc.
