CVE-2017-5130

A heap overflow flaw was found in the libxml2 library. An application compiled with libxml2 using the vulnerable debug-only function xmlMemoryStrdup could be used by an attacker to crash the application or execute arbitrary code with the permission of the user running the application.

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.
