CVSS: 7.2EPSS: 0%CPEs: 17EXPL: 1CVE-2020-26116 – python: CRLF injection via HTTP request method in httplib/http.client
https://notcve.org/view.php?id=CVE-2020-26116
http.client in Python 3.x before 3.5.10, 3.6.x before 3.6.12, 3.7.x before 3.7.9, and 3.8.x before 3.8.5 allows CRLF injection if the attacker controls the HTTP request method, as demonstrated by inserting CR and LF control characters in the first argument of HTTPConnection.request. http.client en Python 3.x antes de la versión 3.5.10, 3.6.x antes de la versión 3.6.12, 3.7.x antes de la versión 3.7.9, y 3.8.x antes de la versión 3.8.5 permite la inyección de CRLF si el atacante controla el método de petición HTTP, como se demuestra insertando caracteres de control CR y LF en el primer argumento de HTTPConnection.request A flaw was found in Python. The built-in modules httplib and http.client (included in Python 2 and Python 3, respectively) do not properly validate CRLF sequences in the HTTP request method, potentially allowing manipulation to the request by injecting additional HTTP headers. The highest threat from this vulnerability is to confidentiality and integrity. • http://lists.opensuse.org/opensuse-security-announce/2020-11/msg00027.html https://bugs.python.org/issue39603 https://lists.debian.org/debian-lts-announce/2020/11/msg00032.html https://lists.debian.org/debian-lts-announce/2023/05/msg00024.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BW4GCLQISJCOEGQNIMVUZDQMIY6RR6CC https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/HDQ2THWU4GPV4Y5H5WW5PFMSWXL2CRFD https://lists.fedoraproject.org/ • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') CWE-113: Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Request/Response Splitting') •

CVSS: 8.2EPSS: 0%CPEs: 4EXPL: 0CVE-2020-16122 – Packagekit's apt backend lets user install untrusted local packages
https://notcve.org/view.php?id=CVE-2020-16122
PackageKit's apt backend mistakenly treated all local debs as trusted. The apt security model is based on repository trust and not on the contents of individual files. On sites with configured PolicyKit rules this may allow users to install malicious packages. El backend apt de PackageKit trató erróneamente a todas las debs locales como confiables. El modelo de seguridad de apt se basa en la confianza del repositorio y no en el contenido de archivos individuales. • https://bugs.launchpad.net/ubuntu/+source/packagekit/+bug/1882098 • CWE-269: Improper Privilege Management CWE-345: Insufficient Verification of Data Authenticity •

A missing CAP_NET_RAW check in NFC socket creation in net/nfc/rawsock.c in the Linux kernel before 5.8.2 could be used by local attackers to create raw sockets, bypassing security mechanisms, aka CID-26896f01467a. Una falta de comprobación de CAP_NET_RAW en la creación de sockets NFC en el archivo net/nfc/rawsock.c en el Kernel de Linux versiones anteriores a 5.8.2, podría ser usada por unos atacantes locales para crear sockets sin procesar, omitiendo los mecanismos de seguridad, también se conoce como CID-26896f01467a. • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00021.html https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.8.2 https://github.com/torvalds/linux/commit/26896f01467a28651f7a536143fe5ac8449d4041 https://lists.debian.org/debian-lts-announce/2020/09/msg00025.html https://lists.debian.org/debian-lts-announce/2020/10/msg00032.html https://lists.debian.org/debian-lts-announce/2020/10/msg00034.html https: • CWE-276: Incorrect Default Permissions •

An issue was discovered in the gon gem before gon-6.4.0 for Ruby. MultiJson does not honor the escape_mode parameter to escape fields as an XSS protection mechanism. To mitigate, json_dumper.rb in gon now does escaping for XSS by default without relying on MultiJson. Se detectó un problema en la gema gon versiones anteriores a gon-6.4.0 para Ruby. MultiJson, no respeta el parámetro escape_mode para escapar de los campos como mecanismo de protección XSS. • https://github.com/gazay/gon/commit/fe3c7b2191a992386dc9edd37de5447a4e809bc7 https://lists.debian.org/debian-lts-announce/2020/09/msg00018.html https://usn.ubuntu.com/4560-1 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
