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.) |

Logged In: YES user_id=6380 OK, checked in for 2.3. Keeping this open until I find the time to backport it to 2.2 and 2.1 (or someone else does that). |

Logged In: YES user_id=6380 All backported. (Note that as a side effect of this patch, changes to Modules/Setup[.dist] had to be made and backported to compile the errno module statically, because the patch introduces a dependency on it to distutils and hence to the setup.py script.) |
