CVSS: 7.8EPSS: 0%CPEs: 4EXPL: 0CVE-2021-4041 – Ansible: Improper shell escaping in ansible-runner
https://notcve.org/view.php?id=CVE-2021-4041
A flaw was found in ansible-runner. An improper escaping of the shell command, while calling the ansible_runner.interface.run_command, can lead to parameters getting executed as host's shell command. A developer could unintentionally write code that gets executed in the host rather than the virtual environment. Se ha encontrado un fallo en ansible-runner. Un escape inapropiado del comando shell, mientras es llamado a ansible_runner.interface.run_command, puede conllevar a que los parámetros sean ejecutados como el comando shell del host. • https://access.redhat.com/security/cve/CVE-2021-4041 https://bugzilla.redhat.com/show_bug.cgi?id=2028074 https://github.com/ansible/ansible-runner/commit/3533f265f4349a3f2a0283158cd01b59a6bbc7bd • CWE-20: Improper Input Validation CWE-116: Improper Encoding or Escaping of Output •

CVSS: 7.7EPSS: 0%CPEs: 8EXPL: 0CVE-2022-21682 – flatpak-builder can access files outside the build directory.
https://notcve.org/view.php?id=CVE-2022-21682
Flatpak is a Linux application sandboxing and distribution framework. A path traversal vulnerability affects versions of Flatpak prior to 1.12.3 and 1.10.6. flatpak-builder applies `finish-args` last in the build. At this point the build directory will have the full access that is specified in the manifest, so running `flatpak build` against it will gain those permissions. Normally this will not be done, so this is not problem. However, if `--mirror-screenshots-url` is specified, then flatpak-builder will launch `flatpak build --nofilesystem=host appstream-utils mirror-screenshots` after finalization, which can lead to issues even with the `--nofilesystem=host` protection. • https://github.com/flatpak/flatpak/commit/445bddeee657fdc8d2a0a1f0de12975400d4fc1a https://github.com/flatpak/flatpak/commit/4d11f77aa7fd3e64cfa80af89d92567ab9e8e6fa https://github.com/flatpak/flatpak/security/advisories/GHSA-8ch7-5j3h-g4fx https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/APFTBYGJJVJPFVHRXUW5PII5XOAFI4KH https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/IXKBERLJRYV7KXKGXOLI6IOXVBQNN4DP https://security.gentoo.org/glsa/202312-12 https://www.debian • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
CVSS: 8.6EPSS: 0%CPEs: 7EXPL: 0CVE-2021-43860 – Permissions granted to applications can be hidden from the user at install time
https://notcve.org/view.php?id=CVE-2021-43860
Flatpak is a Linux application sandboxing and distribution framework. Prior to versions 1.12.3 and 1.10.6, Flatpak doesn't properly validate that the permissions displayed to the user for an app at install time match the actual permissions granted to the app at runtime, in the case that there's a null byte in the metadata file of an app. Therefore apps can grant themselves permissions without the consent of the user. Flatpak shows permissions to the user during install by reading them from the "xa.metadata" key in the commit metadata. This cannot contain a null terminator, because it is an untrusted GVariant. • https://github.com/flatpak/flatpak/commit/54ec1a482dfc668127eaae57f135e6a8e0bc52da https://github.com/flatpak/flatpak/commit/65cbfac982cb1c83993a9e19aa424daee8e9f042 https://github.com/flatpak/flatpak/commit/93357d357119093804df05acc32ff335839c6451 https://github.com/flatpak/flatpak/commit/ba818f504c926baaf6e362be8159cfacf994310e https://github.com/flatpak/flatpak/commit/d9a8f9d8ccc0b7c1135d0ecde006a75d25f66aee https://github.com/flatpak/flatpak/releases/tag/1.10.6 https://github.com/flatpak/flatpak/releases/tag/1.12.3 https://github.com/flatpak/ • CWE-269: Improper Privilege Management CWE-276: Incorrect Default Permissions •
