Bug 741496 – <dev-python/pypy3-7.3.2: multiple vulnerabilities

• Product: Gentoo Security
• Status: CONFIRMED ---

[Description Michał Górny 2020-09-10 09:38:54 UTC]

The not-yet-released pypy3.6 version includes all vulnerabilities fixed since CPython v3.6.9rc1.  I'm working on making a patch set.

[Comment 1 Michał Górny 2020-09-10 19:58:25 UTC]

Speaking in CPython commits:

b23c0840ce [3.6] bpo-37228: Fix loop.create_datagram_endpoint()'s usage of SO_REUSEADDR (GH-17311). (GH-17571)
83fc70159b bpo-38576: Disallow control characters in hostnames in http.client (GH-18995) (GH-19002)
69cdeeb93e bpo-39503: CVE-2020-8492: Fix AbstractBasicAuthHandler (GH-18284) (GH-19304)
7df32f844e bpo-39073: validate Address parts to disallow CRLF (GH-19007) (#19224)
f02de961b9 bpo-39603: Prevent header injection in http methods (GH-18485) (GH-21539)


I'm working on getting them fixed upstream.  Either way, the fixes will be part of the upcoming 7.3.2 release.

Oh, and these two (that are already fixed in the hg branch):

[Comment 4 Reva Denis 2020-10-04 04:05:43 UTC]

Well, module 'socket' has no attribute 'sethostname' issue https://bugs.gentoo.org/716998 again reproduces with pypy-7.3.2 and portage 3.0.4-r1
If we fix it we can just stabilize pypy-7.3.2

[Comment 5 John Helmert III 2021-01-06 08:48:17 UTC]

Maintainers, are these vulnerabilities fixed in 7.3.3 (since it appears to be in the process of being stabled)?

[Comment 6 Michał Górny 2021-01-06 10:11:11 UTC]

Yes, I'm pretty sure I've got all the backports upstream.

[Comment 7 John Helmert III 2021-01-09 21:13:53 UTC]

Please cleanup.

[Comment 8 Michał Górny 2021-01-09 21:59:43 UTC]

Removed old versions.
