Subject: [PATCH 1/2] libdw: Check end of attributes list consistently.
|
||||
|
||||
dwarf_child (__libdw_find_attr), dwarf_getabbrevattr[_data] and
|
||||
dwarf_getattrs all assume the end of the attribute list is when
|
||||
both the name (code) and form of the attribute are zero.
|
||||
|
||||
dwarf_getabbrev (__libdw_getabbrev) and dwarf_hasattr assume the
|
||||
end of the attribute list is when either the name (code) or the
|
||||
form of the attribute is zero.
|
||||
|
||||
The DWARF spec says: "The series of attribute specifications ends
|
||||
with an entry containing 0 for the name and 0 for the form." So
|
||||
the first check is correct.
|
||||
|
||||
Make sure dwarf_getabbrev and dwarf_hasattr use the same check.
|
||||
This is important since all other functions expect dwarf_getabbrev
|
||||
(__libdw_getabbrev) to have done a data sanity check of the attribute.
|
||||
So if the ending condition is different it could cause a crash.

Subject: [PATCH 2/2] libelf: Return error if elf_compress_gnu is used on
|
||||
SHF_COMPRESSED section.
|
||||
|
||||
Compressing a section that is already compressed is fine, but useless.
|
||||
But it isn't possible to gnu compress (or decompress) a SHF_COMPRESSED
|
||||
section since there is no state kept that would tell if the section was
|
||||
first GNU compressed or first gabi compressed. Calling elf_compress_gnu
|
||||
on a section and then calling elf_compress on it to decompress it twice
|
||||
could cause a crash (the other way around is fine). Just disallow it.
