CVE-2022-48560 – python: use after free in heappushpop() of heapq module
https://notcve.org/view.php?id=CVE-2022-48560
A use-after-free exists in Python through 3.9 via heappushpop in heapq. A use-after-free vulnerability was found in Python via the heappushpop function in the heapq module. This flaw allows an attacker to submit a specially crafted request, causing a service disruption that leads to a denial of service attack. • https://bugs.python.org/issue39421 https://lists.debian.org/debian-lts-announce/2023/09/msg00022.html https://lists.debian.org/debian-lts-announce/2023/10/msg00017.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/JZ5OOBWNYWXFTZDMCGHJVGDLDTHLWITJ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/VO7Y2YZSDK3UYJD2KBGLXRTGNG6T326J https://security.netapp.com/advisory/ntap-20230929-0008 https://access.redhat.com/security/cve/CVE-2022 • CWE-416: Use After Free •
CVE-2023-38898
https://notcve.org/view.php?id=CVE-2023-38898
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 •
CVE-2023-36632
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 •
