An issue in Python cpython v.3.7 allows an attacker to obtain sensitive information via the _asyncio._swap_current_task component. NOTE: this is disputed by the vendor because (1) neither 3.7 nor any other release is affected (it is a bug in some 3.12 pre-releases); (2) there are no common scenarios in which an adversary can call _asyncio._swap_current_task but does not already have the ability to call arbitrary functions; and (3) there are no common scenarios in which sensitive information, which is not already accessible to an adversary, becomes accessible through this bug. Un problema en Python cpython v.3.7 permite a un atacante obtener información sensible a través del componente _asyncio. • https://github.com/python/cpython/issues/105987 •

https://notcve.org/view.php?id=CVE-2023-36632
The legacy email.utils.parseaddr function in Python through 3.11.4 allows attackers to trigger "RecursionError: maximum recursion depth exceeded while calling a Python object" via a crafted argument. This argument is plausibly an untrusted value from an application's input data that was supposed to contain a name and an e-mail address. NOTE: email.utils.parseaddr is categorized as a Legacy API in the documentation of the Python email package. Applications should instead use the email.parser.BytesParser or email.parser.Parser class. NOTE: the vendor's perspective is that this is neither a vulnerability nor a bug. • https://docs.python.org/3/library/email.html https://docs.python.org/3/library/email.utils.html https://github.com/Daybreak2019/PoC_python3.9_Vul/blob/main/RecursionError-email.utils.parseaddr.py https://github.com/python/cpython/issues/103800 • CWE-674: Uncontrolled Recursion •

CVSS: 6.1EPSS: 0%CPEs: 2EXPL: 1CVE-2023-32681 – Unintended leak of Proxy-Authorization header in requests
https://notcve.org/view.php?id=CVE-2023-32681
Requests is a HTTP library. Since Requests 2.3.0, Requests has been leaking Proxy-Authorization headers to destination servers when redirected to an HTTPS endpoint. This is a product of how we use `rebuild_proxies` to reattach the `Proxy-Authorization` header to requests. For HTTP connections sent through the tunnel, the proxy will identify the header in the request itself and remove it prior to forwarding to the destination server. However when sent over HTTPS, the `Proxy-Authorization` header must be sent in the CONNECT request as the proxy has no visibility into the tunneled request. • https://github.com/hardikmodha/POC-CVE-2023-32681 https://github.com/psf/requests/commit/74ea7cf7a6a27a4eeb2ae24e162bcc942a6706d5 https://github.com/psf/requests/releases/tag/v2.31.0 https://github.com/psf/requests/security/advisories/GHSA-j8r2-6x86-q33q https://lists.debian.org/debian-lts-announce/2023/06/msg00018.html https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/AW7HNFGYP44RT3DUDQXG2QT3OEV2PJ7Y https://lists.fedoraproject.org/archives/list/package-announce@lists.fedorap • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-402: Transmission of Private Resources into a New Sphere ('Resource Leak') •
CVSS: 5.3EPSS: 0%CPEs: 2EXPL: 1CVE-2023-27043 – python: Parsing errors in email/_parseaddr.py lead to incorrect value in email address part of tuple
https://notcve.org/view.php?id=CVE-2023-27043
The email module of Python through 3.11.3 incorrectly parses e-mail addresses that contain a special character. The wrong portion of an RFC2822 header is identified as the value of the addr-spec. In some applications, an attacker can bypass a protection mechanism in which application access is granted only after verifying receipt of e-mail to a specific domain (e.g., only @company.example.com addresses may be used for signup). This occurs in email/_parseaddr.py in recent versions of Python. • http://python.org https://github.com/python/cpython/issues/102988 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/4ZAEFSFZDNBNJPNOUTLG5COISGQDLMGV https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/75DTHSTNOFFNAWHXKMDXS7EJWC6W2FUC https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ARI7VDSNTQVXRQFM6IK5GSSLEIYV4VZH https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BQAKLUJMHFGVBRDPEY5 • CWE-20: Improper Input Validation •
