[issue2004] tarfile extractall() allows local attacker to overwrite files while extracting
Lars Gustäbel added the comment: This was fixed in the trunk in r53526 about a year ago following issue1507247. I did not backport it to 2.5 at that time, because it would have changed existing behaviour. If there are no objections I could do this now. The os.mkdir() call in TarFile.makedir() uses the default mode, but the real mode from the TarInfo object is applied two instructions later in TarFile._extract_member(). I have nothing against using 0700 in TarFile.makedir(). The os.makedirs() call in _extract_member() (trunk) is fine. It creates missing directories that are not part of the archive with default permissions, that is mode 0777 with the current umask masked out. I attached a patchset against the release25-maint branch and the trunk that is supposed to fix the issue and harmonizes the code between the two versions.

[issue1757072] Zipfile robustness
Chris Mellon added the comment: I agree that the zipfile is out of spec. Here are my arguments in favor of making the change anyway: Existing zip tools like 7zip, pkzip, and winzip handle these files as expected As far as I know, it won't break any valid zipfiles. Because the fix necessary is buried inside a private function in the zipfile module, it's difficult to monkey-patch the behavior into place and it's quite hard to figure out what needs to be done. _ Tracker [EMAIL PROTECTED] http://bugs.python.org/issue1757072 _ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue2009] Grammar change to prevent shift/reduce problem with varargslist
New submission from Andrew Dalke:
I wrote a translator from the CFG used in the Grammar file into a form for PLY.
I
found one problem with
varargslist: ((fpdef ['=' test] ',')*
('*' NAME [',' '**' NAME] | '**' NAME) |
fpdef ['=' test] (',' fpdef ['=' test])* [','])
This grammar definition is ambiguous until the presence/lack of a *. PLY
complains:
state 469
(28) varargslist - fpdef EQUAL test COMMA .
(32) varargslist_star - fpdef EQUAL test COMMA .
(35) varargslist_star3 - COMMA . fpdef
(36) varargslist_star3 - COMMA . fpdef EQUAL test
(39) fpdef - . NAME
(40) fpdef - . LPAR fplist RPAR
! shift/reduce conflict for NAME resolved as shift.
! shift/reduce conflict for LPAR resolved as shift.
RPARreduce using rule 28 (varargslist - fpdef EQUAL test COMMA
.)
COLON reduce using rule 28 (varargslist - fpdef EQUAL test COMMA
.)
STARreduce using rule 32 (varargslist_star - fpdef EQUAL test
COMMA .)
DOUBLESTAR reduce using rule 32 (varargslist_star - fpdef EQUAL test
COMMA .)
NAMEshift and go to state 165
LPARshift and go to state 163
! NAME[ reduce using rule 32 (varargslist_star - fpdef EQUAL
test
COMMA
.) ]
! LPAR[ reduce using rule 32 (varargslist_star - fpdef EQUAL
test
COMMA
.) ]
fpdef shift and go to state 515
My fix was to use this definition when I did the translation.
varargslist: ((fpdef ['=' test] (',' fpdef ['=' test])*
(',' '*' NAME [',' '**' NAME] | ',' '**' NAME | [','])) |
('*' NAME [',' '**' NAME]) |
('**' NAME))
So far I've not found a functional difference between these two definitions,
and
the only change to ast.c is to update the comment based on this section.
By making this change it would be easier for the handful of people who write
parsers for Python based on a yacc-like look-ahead(1) parser to use that file
more
directly.

[issue2011] compiler.parse(1; ) adds unexpected extra Discard(Const(None)) to parse tree
Andrew Dalke added the comment: This really is a minor point. I don't track the 3K list and I see now that the compiler module won't be in Python 3k - good riddance - so feel free to discard this as well as the other open compiler module bugs. I want to experiment with adding instrumentation for branch coverage. To do that I want to get the character ranges of each term in the AST. The Python compiler module doesn't keep track of that so I'm developing a new parser based on PLY. I've developed it and I'm now cross-checking the generated ASTs to verify they are identical. In this case the compiler module generates an extra node in the AST so I had to add backwards compatibility support. __ Tracker [EMAIL PROTECTED] http://bugs.python.org/issue2011 __ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
