Description Florian Weimer 2018-02-09 12:28:42 UTC 
net-snmp-5.7.3-33.fc28 does not fully apply the Fedora build flags from redhat-rpm-config.  Specifically, /usr/bin/snmpget and other programs are not linked as PIE:

# eu-readelf -h /usr/bin/snmpget
ELF Header:
  Magic:   7f 45 4c 46 02 01 01 00 00 00 00 00 00 00 00 00
  Class:                             ELF64
  Data:                              2's complement, little endian
  Ident Version:                     1 (current)
  OS/ABI:                            UNIX - System V
  ABI Version:                       0
  Type:                              EXEC (Executable file)
  Machine:                           AMD x86-64
  Version:                           1 (current)
  Entry point address:               0x401180
  Start of program headers:          64 (bytes into file)
  Start of section headers:          9808 (bytes into file)
  Flags:                             
  Size of this header:               64 (bytes)
  Size of program header entries:    56 (bytes)
  Number of program headers entries: 11
  Size of section header entries:    64 (bytes)
  Number of section headers entries: 29
  Section header string table index: 28

The type should be DYN, not EXEC.
