vim: Integer overflow at a u_read_undo memory allocation site

CVE-2017-6349 [CRITICAL] CWE-190 vim: Integer overflow at a u_read_undo memory allocation site
vim: Integer overflow at a u_read_undo memory allocation site
An integer overflow at a u_read_undo memory allocation site would occur for vim before patch 8.0.0377, if it does not properly validate values for tree length when reading a corrupted undo file, which may lead to resultant buffer overflows.
An integer overflow flaw was found in the way vim handled undo files. This bug could result in vim crashing when trying to process corrupted undo files.
