It has been identified that the runtime linker allows privilege escalation via arbitrary file writes with elevated privileges programs. When MALLOCOPTIONS and MALLOCBUCKETS environment variables are set with bucket statistics options and by executing certain setuid programs, a non-privileged user may able to create a root owned file with 666 permission.

In AIX6.1 and above, a local user can also exploit this error using the _LIB_INIT_DBG and _LIB_INIT_DBG_FILE environment variables.
