    SF patch 590294: os._execvpe security fix (Zack Weinberg). · aed51d81
    Guido van Rossum yazdı
    1) Do not attempt to exec a file which does not exist
    just to find out what error the operating system
    returns. This is an exploitable race on all platforms
    that support symbolic links.
    
    2) Immediately re-raise the exception if we get an
    error other than errno.ENOENT or errno.ENOTDIR. This
    may need to be adapted for other platforms.
    
    (As a security issue, this should be considered for 2.1
    and 2.2 as well as 2.3.)
