If you + still have the crash described just above, then the verification is + failed. + + Additionally, a dep8 test covering this test case has been added to the + package. + + [ Where problems could occur ] + + Considering that the patch is just a buffer size increase by 1, it should be pretty safe. However, as with every update, there is always a chance that something goes wrong, and `zip` is even more broken than before. The dep8 test added in this new version at least verifies that a basic usage of the tool is working. + Additionally, since this is a simple CLI tool, it's quite easy to verify that it's not completely broken. + + [ Other Info ] + + N/A + + + [Original description] + + Running zip command with -T -TT arguments causes zip process to crash + due to buffer overflow.
