            Bug ID: 19868
           Summary: nss_dns: netent code does not skip over non-PTR
                    records
           Product: glibc
           Version: 2.24
            Status: NEW
          Severity: normal
          Priority: P2
         Component: network
          Assignee: unassigned at sourceware dot org
          Reporter: fweimer at redhat dot com
  Target Milestone: ---
             Flags: security-

If a non-PTR record is encountered, the code fails to skip over the RDATA
portion of the ignored record.  As a result, the getnetbyname and getnetbyaddr
implementations cannot extract PTR records from responses also containing CNAME
records.
