Subject: [PATCH] readelf: Skip trying to uncompress sections without a name
|
|
|
|
When combining eu-readelf -z with -x or -p to dump the data or strings
|
|
in an (corrupted ELF) unnamed numbered section eu-readelf could crash
|
|
trying to check whether the section name starts with .zdebug. Fix this
|
|
by skipping sections without a name.
|
|
|
|
* src/readelf.c (dump_data_section): Don't try to gnu decompress a
|
|
section without a name.
|
|
(print_string_section): Likewise.
