Description Doran Moppert 2016-06-21 23:33:05 EDT
An out-of-bounds read due to incorrect sign extension was found in
libarchive.  A specially crafted ZIP file could cause libarchive to
crash.  A few bytes of heap memory within a 256-byte region could
potentially be exposed.

Upstream bug:
    https://github.com/libarchive/libarchive/issues/514

Upstream fix:
    https://github.com/libarchive/libarchive/commit/9e0689c


libarchive-2.8 does not include support for "Info-Zip Unix extra field
(type 3)", where this flaw was found, and is thus unaffected.
