+Subject: [PATCH] libdw: Simplify __libdw_getabbrev and fix dwarf_offabbrev
+ issue
+
+__libdw_getabbrev could crash on reading a bad abbrev by trying to
+deallocate memory it didn't allocate itself. This could happen because
+dwarf_offabbrev would supply its own memory when calling
+__libdw_getabbrev. No other caller did this.
+
+Simplify the __libdw_getabbrev common code by not taking external
+memory to put the abbrev result in (this would also not work correctly
+if the abbrev was already cached). And make dwarf_offabbrev explicitly
+copy the result (if there was no error or end of abbrev).
+
+     * libdw/dwarf_getabbrev.c (__libdw_getabbrev): Don't take
+     Dwarf_Abbrev result argument. Always just allocate abb when
+     abbrev not found in cache.
+     (dwarf_getabbrev): Don't pass NULL as last argument to
+     __libdw_getabbrev.
+    * libdw/dwarf_tag.c (__libdw_findabbrev): Likewise.
+    * libdw/dwarf_offabbrev.c (dwarf_offabbrev): Likewise. And copy
+    abbrev into abbrevp on success.
+    * libdw/libdw.h (dwarf_offabbrev): Document return values.
+    * libdw/libdwP.h (__libdw_getabbrev): Don't take Dwarf_Abbrev
+    result argument.

+
+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.
