than 0.2.149.29.  Such versions are reportedly affected by several
issues :

  - A buffer overflow involving long filenames that display
    in the 'Save As...' dialog could lead to arbitrary code
    execution (Issue #1414).

  - A buffer overflow in handling of link targets displayed
    in the status area when a user hovers over a link could
    lead to arbitrary code execution (Fix #1797).

  - An out-of-bounds memory read when parsing URLs ending in
    ':%' could cause the application itself to crash (Issue
    #122).

  - The default Downloads directory is set to Desktop, which
    could lead to malicious cluttering of the desktop with
    unwanted downloads and even execution of arbitrary
    programs (Fix #17933).");
