Integer to and from text conversions via CPython's bignum int type is not safe against denial of service attacks due to malicious input. Very large input strings with hundred thousands of digits can consume several CPU seconds.

This PR comes fresh from a pile of work done in our private PSRT security response team repo.

This backports #96499 aka 511ca94

wait for #96537 to be integrated into this PR before merging, i'll remove the do-not-merge label then.

pythongh-95778: Correctly pre-check for int-to-str conversion (python… …
17bd053 
…#96537)

Converting a large enough `int` to a decimal string raises `ValueError` as expected. However, the raise comes _after_ the quadratic-time base-conversion algorithm has run to completion. For effective DOS prevention, we need some kind of check before entering the quadratic-time loop. Oops! =)

The quick fix: essentially we catch _most_ values that exceed the threshold up front. Those that slip through will still be on the small side (read: sufficiently fast), and will get caught by the existing check so that the limit remains exact.

The justification for the current check. The C code check is:
```c
max_str_digits / (3 * PyLong_SHIFT) <= (size_a - 11) / 10
```

In GitHub markdown math-speak, writing $M$ for `max_str_digits`, $L$ for `PyLong_SHIFT` and $s$ for `size_a`, that check is:
$$\left\lfloor\frac{M}{3L}\right\rfloor \le \left\lfloor\frac{s - 11}{10}\right\rfloor$$

From this it follows that
$$\frac{M}{3L} < \frac{s-1}{10}$$
hence that
$$\frac{L(s-1)}{M} > \frac{10}{3} > \log_2(10).$$
So
$$2^{L(s-1)} > 10^M.$$
But our input integer $a$ satisfies $|a| \ge 2^{L(s-1)}$, so $|a|$ is larger than $10^M$. This shows that we don't accidentally capture anything _below_ the intended limit in the check.

@tiran can wasm32 failures be ignored here? This is a 3.8 backport and that version is not supported on WASM?

Those fail to build with errors like Invalid configuration wasm32-unknown-emscripten': system emscripten' not recognized , configure: error: cross build not supported for wasm32-unknown-emscripten, and configure: WARNING: unrecognized options: --with-emscripten-target, --enable-wasm-dynamic-linking, --disable-wasm-pthreads.

Unfortunately, there are legitimate failures here.

At least the ASAN and USAN failures are definitely related to this change, the others might be related indirectly.

what makes you think those are related to this change?

Arch ASAN 3.8 both: https://buildbot.python.org/all/#/builders/590 and https://buildbot.python.org/all/#/builders/580 show red for six months on 3.8.

and Arch USAN has not 3.8 bot and history at all.

If you want a baseline for those bots on 3.8 with no changes, I ran them via #96586.

We looked into this. 3.7 and 3.8 are typically not running address and undefined behavior sanitizers on buildbots. The label-driven trigger on PRs is overly broad and runs configurations that aren't used by us for the oldest branches in regular testing. At least 3.8 fails ASAN and UBSAN without #96503 applied as well. I'm landing this.

⚠️⚠️⚠️ Buildbot failure ⚠️⚠️⚠️

Hi! The buildbot s390x Fedora Clang 3.8 has failed when building commit b5e331f.

What do you need to do:

  1. Don't panic.
  2. Check the buildbot page in the devguide if you don't know what the buildbots are or how they work.
  3. Go to the page of the buildbot that failed (https://buildbot.python.org/all/#builders/235/builds/78) and take a look at the build logs.
  4. Check if the failure is related to this commit (b5e331f) or if it is a false positive.
  5. If the failure is related to this commit, please, reflect that on the issue and make a new Pull Request with a fix.

You can take a look at the buildbot page here:

https://buildbot.python.org/all/#builders/235/builds/78

Failed tests:

  • test_pickletools
  • test_pickle

Note: switching to 'b5e331fdb38684808ffc540d53e8595bdc408b89'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false

Buildbot failure

Hi! The buildbot x86 Gentoo Non-Debug with X 3.8 has failed when building commit b5e331f.

[...]

Failed tests:

  • test_gdb

FYI, we're skipping test_gdb on Gentoo for as long as I remember (i.e. it came before me), so that one probably can be skipped from buildbot testing as well.
