Yes, I think you interpreted the ELF header correctly. e_shoff in the
ELF header is 0x4F08, but the section header table does not start at
this offset of the file. In ELF, the section header for index 0 is
reserved for SHN_UNDEF and should be all zeros. It's very likely that
the section table starts at offset 0x4F14. You may modify the file and
use readelf to see if it produce a reasonable output.


You may file a bug report in http://sources.redhat.com/bugzilla/ with
the information about how this problem can be reproduced.
