Subject: [PATCH] Fix CVE-2019-14866
|
||||
|
||||
* src/copyout.c (to_ascii): Additional argument nul controls whether
|
||||
to add the terminating nul character.
|
||||
(field_width_error): Improve diagnostics: print the actual and the
|
||||
maximum allowed field value.
|
||||
* src/extern.h (to_ascii, field_width_error): New prototypes.
|
||||
* src/tar.c (to_oct): Remove.
|
||||
(to_oct_or_error): New function.
|
||||
(TO_OCT): New macro.
|
||||
(write_out_tar_header): Use TO_OCT and to_ascii. Return 0 on
|
||||
success, 1 on error.
|
||||

||||

Subject: [PATCH] cpio: add option to add file metadata in copy-out mode
|
||||
|
||||
This patch adds the -e <type> option to include file metadata in the
|
||||
image. At the moment, only the xattr type is supported.
|
||||
|
||||
If the xattr type is selected, the patch includes an additional file for
|
||||
each file passed to stdin, with special name 'METADATA!!!'. The
|
||||
additional file might contain multiple metadata records. The format of
|
||||
each record is:
|
||||
|
||||
<metadata len (ASCII, 8 chars)><version><type><metadata>
|
||||
|
||||
The format of metadata for the xattr type is:
|
||||
|
||||
<xattr name>\0<xattr value>
|
||||
