* bpo-38804: Fix REDoS in http.cookiejar (GH-17157) (GH-17345)Victor Stinner2019-11-244-8/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | Rather than requiring the path to blurb and/or sphinx-build to be specified to the make rule, enhance the Doc/Makefile to look for each first in a virtual environment created by make venv and, if not found, look on the normal process PATH. This allows the Doc/Makefile to take advantage of an installed spinx-build or blurb and, thus, do the right thing most of the time. Also, make the directory for the venv be configurable and document the `make venv` target..

| | | | | | | | | | | | | validation and encoding behavior (GH-16476) Backporting this change, I observe a couple of things: 1. The _encode_request call is no longer meaningful because the request construction will implicitly encode the request using the default encoding when the format string is used (request = '%s %s %s'...). In order to keep the code as consistent as possible, I decided to include the call as a pass-through. I'd be just as happy to remove it entirely, but I'll leave that up to the reviewer to decide. It's okay that this functionality is disabled on Python 2 because this functionality was mainly around bpo-36274, which was mainly a concern with the transition to Python 3. 2. Because _encode_request is no longer meaningful, neither is the test for it, so I've removed that test. Therefore, the meaningful part of this test is that for bpo-38216, adding a (underscore-protected) hook to customize/disable validation.

* bpo-38106: Fix race in pthread PyThread_release_lock() (GH-16047)Kirill Smelkov2019-10-032-6/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix race in PyThread_release_lock that was leading to memory corruption and deadlocks. The fix applies to POSIX systems where Python locks are implemented with mutex and condition variable because POSIX semaphores are either not provided, or are known to be broken. One particular example of such system is macOS. On Darwin, even though this is considered as POSIX, Python uses mutex+condition variable to implement its lock, and, as of 2019-08-28, Py2.7 implementation, even though similar issue was fixed for Py3 in 2012, contains synchronization bug: the condition is signalled after mutex unlock while the correct protocol is to signal condition from under mutex: https://github.com/python/cpython/blob/v2.7.16-127-g0229b56d8c0/Python/thread_pthread.h#L486-L506 https://github.com/python/cpython/commit/187aa545165d (py3 fix) PyPy has the same bug for both pypy2 and pypy3: https://bitbucket.org/pypy/pypy/src/578667b3fef9/rpython/translator/c/src/thread_pthread.c#lines-443:465 https://bitbucket.org/pypy/pypy/src/5b42890d48c3/rpython/translator/c/src/thread_pthread.c#lines-443:465 Signalling condition outside of corresponding mutex is considered OK by POSIX, but in Python context it can lead to at least memory corruption if we consider the whole lifetime of python level lock. For example the following logical scenario: T1 T2 sema = Lock() sema.acquire() sema.release() sema.acquire() free(sema) ... can translate to the next C-level calls: T1 T2 # sema = Lock() sema = malloc(...) sema.locked = 0 pthread_mutex_init(&sema.mut) pthread_cond_init (&sema.lock_released) # sema.acquire() pthread_mutex_lock(&sema.mut) # sees sema.locked == 0 sema.locked = 1 pthread_mutex_unlock(&sema.mut) # sema.release() pthread_mutex_lock(&sema.mut) sema.locked = 0 pthread_mutex_unlock(&sema.mut) # OS scheduler gets in and relinquishes control from T2 # to another process ... # second sema.acquire() pthread_mutex_lock(&sema.mut) # sees sema.locked == 0 sema.locked = 1 pthread_mutex_unlock(&sema.mut) # free(sema) pthread_mutex_destroy(&sema.mut) pthread_cond_destroy (&sema.lock_released) free(sema) # ... e.g. malloc() which returns memory where sema was ... # OS scheduler returns control to T2 # sema.release() continues # # BUT sema was already freed and writing to anywhere # inside sema block CORRUPTS MEMORY. In particular if # _another_ python-level lock was allocated where sema # block was, writing into the memory can have effect on # further synchronization correctness and in particular # lead to deadlock on lock that was next allocated. pthread_cond_signal(&sema.lock_released) Note that T2.pthread_cond_signal(&sema.lock_released) CORRUPTS MEMORY as it is called when sema memory was already freed and is potentially reallocated for another object. The fix is to move pthread_cond_signal to be done under corresponding mutex: # sema.release() pthread_mutex_lock(&sema.mut) sema.locked = 0 pthread_cond_signal(&sema.lock_released) pthread_mutex_unlock(&sema.mut) To do so this patch cherry-picks thread_pthread.h part of the following 3.2 commit: commit 187aa545165d8d5eac222ecce29c8a77e0282dd4 Author: Kristján Valur Jónsson <kristjan@ccpgames.com> Date: Tue Jun 5 22:17:42 2012 +0000 Signal condition variables with the mutex held. Destroy condition variables before their mutexes.

It was discussed in 2001 with original code author[2], but the code was still considered to be race-free. In 2010 the place where pthread_cond_signal should be - before or after pthread_mutex_unlock - was discussed with the rationale to avoid threads bouncing[3,4,5], and in 2012 pthread_cond_signal was moved to be called from under mutex, but only for CPython3[6,7]. In 2019 the bug was (re-)discovered while testing Pygolang[8] on macOS with CPython2 and PyPy2 and PyPy3.
