1ef4c32 Anthony Sottile 27 November 2019, 04:54:46 UTC Be more specific about the `.so` gitignore patterns (GH-17328) In GH-15823 the pattern was changed from `libpython*.so*` to `*.so*` which matches a bit too greedily for some packagers. For instance this trips up `debian/README.source`. A more specific pattern fixes this issue. 27 November 2019, 04:54:46 UTC

This was caused by the specified index of an invalid input which did not exist in the memo structure, where the pickle stores what objects it has seen. The malformed input would have caused either a `BINGET` or `LONG_BINGET` load from the memo, leading to a `KeyError` as the determined index was bogus. https://bugs.python.org/issue38876 https://bugs.python.org/issue38876 24 November 2019, 19:15:08 UTC

14a89c4 PypeBros 22 November 2019, 23:19:08 UTC bpo-38686: fix HTTP Digest handling in request.py (#17045) * fix HTTP Digest handling in request.py There is a bug triggered when server replies to a request with `WWW-Authenticate: Digest` where `qop="auth,auth-int"` rather than mere `qop="auth"`. Having both `auth` and `auth-int` is legitimate according to the `qop-options` rule in §3.2.1 of [[https://www.ietf.org/rfc/rfc2617.txt|RFC 2617]]: > qop-options = "qop" "=" <"> 1#qop-value <"> > qop-value = "auth" | "auth-int" | token > **qop-options**: [...] If present, it is a quoted string **of one or more** tokens indicating the "quality of protection" values supported by the server. The value `"auth"` indicates authentication; the value `"auth-int"` indicates authentication with integrity protection This is description confirmed by the definition of the [//n//]`#`[//m//]//rule// extended-BNF pattern defined in §2.1 of [[https://www.ietf.org/rfc/rfc2616.txt|RFC 2616]] as 'a comma-separated list of //rule// with at least //n// and at most //m// items'. When this reply is parsed by `get_authorization`, request.py only tests for identity with `'auth'`, failing to recognize it as one of the supported modes the server announced, and claims that `"qop 'auth,auth-int' is not supported"`. * 📜🤖 Added by blurb_it. * bpo-38686 review fix: remember why. * fix trailing space in Lib/urllib/request.py Co-Authored-By: Brandt Bucher <brandtbucher@gmail.com> 22 November 2019, 23:19:08 UTC

2ec1a1b Victor Stinner 22 November 2019, 20:54:33 UTC bpo-38858: new_interpreter() uses pycore_init_import_warnings() (GH-17353) 22 November 2019, 20:54:33 UTC
2582d46 Victor Stinner 22 November 2019, 18:24:49 UTC bpo-38858: new_interpreter() reuses pycore_init_builtins() (GH-17351) new_interpreter() now calls _PyBuiltin_Init() to create the builtins module and calls _PyImport_FixupBuiltin(), rather than using _PyImport_FindBuiltin(tstate, "builtins"). pycore_init_builtins() is now responsible to initialize intepr->builtins_copy: inline _PyImport_Init() and remove this function. 22 November 2019, 18:24:49 UTC
82c83bd Victor Stinner 22 November 2019, 17:52:27 UTC bpo-38858: _PyImport_FixupExtensionObject() handles subinterpreters (GH-17350) If _PyImport_FixupExtensionObject() is called from a subinterpreter, leave extensions unchanged and don't copy the module dictionary into def->m_base.m_copy. 22 November 2019, 17:52:27 UTC
42bc60e Callum Ward 22 November 2019, 16:57:14 UTC closes bpo-29275: Remove Y2K reference from time module docs (GH-17321) The Y2K reference is not needed as it only points out that Python's use of C standard functions doesn't generally suffer from Y2K issues; the point regarding conventions for conversion of 2-digit years in :func:`strptime` is still valid. 22 November 2019, 16:57:14 UTC

1b779bf bcaller 22 November 2019, 14:22:11 UTC bpo-38804: Fix REDoS in http.cookiejar (GH-17157) The regex http.cookiejar.LOOSE_HTTP_DATE_RE was vulnerable to regular expression denial of service (REDoS). LOOSE_HTTP_DATE_RE.match is called when using http.cookiejar.CookieJar to parse Set-Cookie headers returned by a server. Processing a response from a malicious HTTP server can lead to extreme CPU usage and execution will be blocked for a long time. The regex contained multiple overlapping \s* capture groups. Ignoring the ?-optional capture groups the regex could be simplified to \d+-\w+-\d+(\s*\s*\s*)$ Therefore, a long sequence of spaces can trigger bad performance. Matching a malicious string such as LOOSE_HTTP_DATE_RE.match("1-c-1" + (" " * 2000) + "!") caused catastrophic backtracking. The fix removes ambiguity about which \s* should match a particular space. You can create a malicious server which responds with Set-Cookie headers to attack all python programs which access it e.g. from http.server import BaseHTTPRequestHandler, HTTPServer def make_set_cookie_value(n_spaces): spaces = " " * n_spaces expiry = f"1-c-1{spaces}!" return f"b;Expires={expiry}" class Handler(BaseHTTPRequestHandler): def do_GET(self): self.log_request(204) self.send_response_only(204) # Don't bother sending Server and Date n_spaces = ( int(self.path[1:]) # Can GET e.g. /100 to test shorter sequences if len(self.path) > 1 else 65506 # Max header line length 65536 ) value = make_set_cookie_value(n_spaces) for i in range(99): # Not necessary, but we can have up to 100 header lines self.send_header("Set-Cookie", value) self.end_headers() if __name__ == "__main__": HTTPServer(("", 44020), Handler).serve_forever() This server returns 99 Set-Cookie headers. Each has 65506 spaces. Extracting the cookies will pretty much never complete. Vulnerable client using the example at the bottom of https://docs.python.org/3/library/http.cookiejar.html : import http.cookiejar, urllib.request cj = http.cookiejar.CookieJar() opener = urllib.request.build_opener(urllib.request.HTTPCookieProcessor(cj)) r = opener.open("http://localhost:44020/") The popular requests library was also vulnerable without any additional options (as it uses http.cookiejar by default): import requests requests.get("http://localhost:44020/") * Regression test for http.cookiejar REDoS If we regress, this test will take a very long time. * Improve performance of http.cookiejar.ISO_DATE_RE A string like "444444" + (" " * 2000) + "A" could cause poor performance due to the 2 overlapping \s* groups, although this is not as serious as the REDoS in LOOSE_HTTP_DATE_RE was. 22 November 2019, 14:22:11 UTC

91daa9d Siwon Kang 22 November 2019, 09:13:05 UTC bpo-38863: Improve is_cgi() in http.server (GH-17312) is_cgi() function of http.server library does not currently handle a cgi script if one of the cgi_directories is located at the sub-directory of given path. Since is_cgi() in CGIHTTPRequestHandler class separates given path into (dir, rest) based on the first seen '/', multi-level directories like /sub/dir/cgi-bin/hello.py is divided into head=/sub, rest=dir/cgi-bin/hello.py then check whether '/sub' exists in cgi_directories = [..., '/sub/dir/cgi-bin']. This patch makes the is_cgi() keep expanding dir part to the next '/' then checking if that expanded path exists in the cgi_directories.

7483451 Benjamin Peterson 20 November 2019, 04:39:14 UTC closes bpo-38712: Add signal.pidfd_send_signal. (GH-17070) This exposes a Linux-specific syscall for sending a signal to a process identified by a file descriptor rather than a pid. For simplicity, we don't support the siginfo_t parameter to the syscall. This parameter allows implementing a pidfd version of rt_sigqueueinfo(2), which Python also doesn't support. 20 November 2019, 04:39:14 UTC

This field exists to not have to pass runtime in addition to tstate to a function. Get runtime from tstate: tstate->interp->runtime. Remove "_PyRuntimeState *runtime" parameter from functions already taking a "PyThreadState *tstate" parameter. _PyGC_Init() first parameter becomes "PyThreadState *tstate". 20 November 2019, 01:27:56 UTC

e0cd8aa Pablo Galindo 19 November 2019, 23:46:49 UTC bpo-37957: Allow regrtest to receive a file with test (and subtests) to ignore (GH-16989) When building Python in some uncommon platforms there are some known tests that will fail. Right now, the test suite has the ability to ignore entire tests using the -x option and to receive a filter file using the --matchfile filter. The problem with the --matchfile option is that it receives a file with patterns to accept and when you want to ignore a couple of tests and subtests, is too cumbersome to lists ALL tests that are not the ones that you want to accept and he problem with -x is that is not easy to ignore just a subtests that fail and the whole test needs to be ignored. For these reasons, add a new option to allow to ignore a list of test and subtests for these situations. 19 November 2019, 23:46:49 UTC

293dd23 Pablo Galindo 19 November 2019, 21:34:03 UTC Remove binding of captured exceptions when not used to reduce the chances of creating cycles (GH-17246) Capturing exceptions into names can lead to reference cycles though the __traceback__ attribute of the exceptions in some obscure cases that have been reported previously and fixed individually. As these variables are not used anyway, we can remove the binding to reduce the chances of creating reference cycles. See for example GH-13135 19 November 2019, 21:34:03 UTC
c6b20be Jake Tesler 19 November 2019, 19:50:12 UTC bpo-38707: Fix for multiprocessing.Process MainThread.native_id (GH-17088) This PR implements a fix for `multiprocessing.Process` objects; the error occurs when Processes are created using either `fork` or `forkserver` as the `start_method`. In these instances, the `MainThread` of the newly created `Process` object retains all attributes from its parent's `MainThread` object, including the `native_id` attribute. The resulting behavior is such that the new process' `MainThread` captures an incorrect/outdated `native_id` (the parent's instead of its own). This change forces the Process object to update its `native_id` attribute during the bootstrap process. cc @vstinner https://bugs.python.org/issue38707 Automerge-Triggered-By: @pitrou 19 November 2019, 19:50:12 UTC
