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 •
CVSS: 6.5EPSS: 0%CPEs: 6EXPL: 1CVE-2022-48564 – python: DoS when processing malformed Apple Property List files in binary format
https://notcve.org/view.php?id=CVE-2022-48564
read_ints in plistlib.py in Python through 3.9.1 is vulnerable to a potential DoS attack via CPU and RAM exhaustion when processing malformed Apple Property List files in binary format. A vulnerability was found in the Python core plistlib library within the read_ints() function in the plistlib.py file. In malformed input, the implementation can be manipulated to create an argument for struct.unpack(). This issue can lead to excessive CPU and memory consumption, resulting in a MemError, as it constructs the 'format' argument for unpack(). This flaw allows an attacker to employ a binary plist input, potentially executing a denial of service (DoS) attack by exhausting CPU and RAM resources. • https://bugs.python.org/issue42103 https://lists.debian.org/debian-lts-announce/2023/10/msg00017.html https://security.netapp.com/advisory/ntap-20230929-0009 https://access.redhat.com/security/cve/CVE-2022-48564 https://bugzilla.redhat.com/show_bug.cgi?id=2249750 • CWE-400: Uncontrolled Resource Consumption •
CVSS: 9.8EPSS: 0%CPEs: 5EXPL: 1CVE-2022-48565 – python: XML External Entity in XML processing plistlib module
https://notcve.org/view.php?id=CVE-2022-48565
An XML External Entity (XXE) issue was discovered in Python through 3.9.1. The plistlib module no longer accepts entity declarations in XML plist files to avoid XML vulnerabilities. A flaw was found in Python caused by improper handling of XML external entity (XXE) declarations by the plistlib module. By using a specially crafted XML content, an attacker could obtain sensitive information by disclosing files specified by parsing URI, and may cause denial of service by resource exhaustion. • https://bugs.python.org/issue42051 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/AFHYAGWBFBNUGWU6XWKBHTCV5NH77MB7 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BAYWJD576JUKLHCWKDLMJSUGTRDKPF3M https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/KZRZRJHWLZ7MOJNPQBWGJVXMVYDC5B • CWE-611: Improper Restriction of XML External Entity Reference •

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 •

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 •
