           Product: OpenLDAP
           Version: 2.6.12
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Keywords: needs_review

         Component: libraries
          Assignee: bugs@openldap.org
          Reporter: mishtitov@gmail.com
  Target Milestone: ---
Return value of a function `ber_memrealloc_x` is dereferenced at
[memory.c:711](https://git.openldap.org/openldap/openldap/-/blob/master/libraries/liblber/m...)
withouth checking for NULL, but it is usually checked for this function. Notice
that `ber_memrealloc_x()` might return NULL when `realloc()` fails. PLease
consider adding a NULL check.
