[ubuntu/trusty-proposed] libtar 1.2.20-3 (Accepted)

[Colin Watson]

libtar (1.2.20-3) unstable; urgency=low

  * no_maxpathlen.patch: Fix two grave bugs in the patch. First,
    th_get_pathname would only allocate as much memory as was needed for
    the first filename encountered, causing heap corruption when/if
    encountering longer filenames later. Second, two variables were mixed
    up in tar_append_tree(). Also, fix a potential memory leak and trim
    the patch a bit.
  * [SECURITY] CVE-2013-4420.patch: When the prefix field is in use, the
    safer_name_suffix() function should certainly be applied to the
    combination of it and the name field, not just on the name field.
  * th_get_size-unsigned-int.patch: Make the th_get_size() macro cast the
    result from oct_to_int() to unsigned int. This is the right fix for
    bug #725938 on 64-bit systems, where a specially crafted tar file
    would not cause an integer overflow, but a memory allocation of almost
    16 exbibytes, which would certainly fail outright without harm.
