CVSS: 7.5EPSS: 0%CPEs: 31EXPL: 1CVE-2022-45061 – python: CPU denial of service via inefficient IDNA decoder
https://notcve.org/view.php?id=CVE-2022-45061
An issue was discovered in Python before 3.11.1. An unnecessary quadratic algorithm exists in one path when processing some inputs to the IDNA (RFC 3490) decoder, such that a crafted, unreasonably long name being presented to the decoder could lead to a CPU denial of service. Hostnames are often supplied by remote servers that could be controlled by a malicious actor; in such a scenario, they could trigger excessive CPU consumption on the client attempting to make use of an attacker-supplied supposed hostname. For example, the attack payload could be placed in the Location header of an HTTP response with status code 302. A fix is planned in 3.11.1, 3.10.9, 3.9.16, 3.8.16, and 3.7.16. • https://github.com/python/cpython/issues/98433 https://lists.debian.org/debian-lts-announce/2023/05/msg00024.html https://lists.debian.org/debian-lts-announce/2023/06/msg00039.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/2AOUKI72ACV6CHY2QUFO6VK2DNMVJ2MB https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/35YDIWCUMWTMDBWFRAVENFH6BLB65D6S https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/4WBZJNS • CWE-400: Uncontrolled Resource Consumption CWE-407: Inefficient Algorithmic Complexity •

https://notcve.org/view.php?id=CVE-2022-40303
An issue was discovered in libxml2 before 2.10.3. When parsing a multi-gigabyte XML document with the XML_PARSE_HUGE parser option enabled, several integer counters can overflow. This results in an attempt to access an array at a negative 2GB offset, typically leading to a segmentation fault. Se descubrió un problema en libxml2 antes de la versión 2.10.3. Al analizar un documento XML de varios gigabytes con la opción de analizador XML_PARSE_HUGE habilitada, varios contadores de enteros pueden desbordarse. • http://seclists.org/fulldisclosure/2022/Dec/21 http://seclists.org/fulldisclosure/2022/Dec/24 http://seclists.org/fulldisclosure/2022/Dec/25 http://seclists.org/fulldisclosure/2022/Dec/26 http://seclists.org/fulldisclosure/2022/Dec/27 https://gitlab.gnome.org/GNOME/libxml2/-/commit/c846986356fc149915a74972bf198abc266bc2c0 https://gitlab.gnome.org/GNOME/libxml2/-/tags/v2.10.3 https://security.netapp.com/advisory/ntap-20221209-0003 https://support.apple.com/kb/HT213531 https:/ • CWE-190: Integer Overflow or Wraparound •

In SQLite 3.31.1, there is an out of bounds access problem through ALTER TABLE for views that have a nested FROM clause. En SQLite versión 3.31.1, se presenta un problema de acceso fuera de límites mediante ALTER TABLE para las vistas que tienen una cláusula FROM anidada An out-of-bounds read vulnerability was found in SQLite. This security flaw occurs when the ALTER TABLE for views has a nested FROM clause. This flaw allows an attacker to triage an out-of-bounds read and access confidential data successfully. • https://security.netapp.com/advisory/ntap-20221111-0007 https://www.sqlite.org/src/info/c431b3fd8fd0f6a6 https://access.redhat.com/security/cve/CVE-2020-35527 https://bugzilla.redhat.com/show_bug.cgi?id=2122329 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
