A use-after-free flaw was found in the Linux kernel’s Bluetooth subsystem in the way user calls connect to the socket and disconnect simultaneously due to a race condition. This flaw allows a user to crash the system or escalate their privileges. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. Se ha encontrado un fallo de uso de memoria previamente liberada en el subsistema Bluetooth del kernel de Linux en la forma en que las llamadas de usuario son conectadas al socket y son desconectadas simultáneamente debido a una condición de carrera. Este fallo permite a un usuario bloquear el sistema o escalar sus privilegios. • https://bugzilla.redhat.com/show_bug.cgi?id=1999544 https://lists.debian.org/debian-lts-announce/2022/03/msg00011.html https://lists.debian.org/debian-lts-announce/2022/03/msg00012.html https://lore.kernel.org/lkml/20211115165435.133245729%40linuxfoundation.org https://security.netapp.com/advisory/ntap-20220318-0009 https://www.debian.org/security/2022/dsa-5096 https://www.openwall.com/lists/oss-security/2021/09/15/4 https://www.oracle.com/security-alerts/cpujul2022.html https:/ • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •

The Samba vfs_fruit module uses extended file attributes (EA, xattr) to provide "...enhanced compatibility with Apple SMB clients and interoperability with a Netatalk 3 AFP fileserver." Samba versions prior to 4.13.17, 4.14.12 and 4.15.5 with vfs_fruit configured allow out-of-bounds heap read and write via specially crafted extended file attributes. A remote attacker with write access to extended file attributes can execute arbitrary code with the privileges of smbd, typically root. El módulo vfs_fruit de Samba usa atributos de archivo extendidos (EA, xattr) para proporcionar "...compatibilidad mejorada con los clientes SMB de Apple e interoperabilidad con un servidor de archivos AFP de Netatalk 3". Samba versiones anteriores a 4.13.17, 4.14.12 y 4.15.5 con vfs_fruit configurado permiten una lectura y escritura fuera de límites de la pila por medio de atributos de archivo extendidos especialmente diseñados. • https://github.com/horizon3ai/CVE-2021-44142 https://github.com/gudyrmik/CVE-2021-44142 https://github.com/hrsman/Samba-CVE-2021-44142 https://bugzilla.samba.org/show_bug.cgi?id=14914 https://kb.cert.org/vuls/id/119678 https://security.gentoo.org/glsa/202309-06 https://www.samba.org/samba/security/CVE-2021-44142.html https://www.zerodayinitiative.com/blog/2022/2/1/cve-2021-44142-details-on-a-samba-code-execution-bug-demonstrated-at-pwn2own-austin https://access.redhat&# • CWE-125: Out-of-bounds Read CWE-787: Out-of-bounds Write •

In strongSwan before 5.9.5, a malicious responder can send an EAP-Success message too early without actually authenticating the client and (in the case of EAP methods with mutual authentication and EAP-only authentication for IKEv2) even without server authentication. En strongSwan versiones anteriores a 5.9.5, un respondedor malicioso puede enviar un mensaje EAP-Success demasiado pronto sin autenticar realmente al cliente y (en el caso de los métodos EAP con autenticación mutua y autenticación sólo EAP para IKEv2) incluso sin autenticación del servidor • https://www.strongswan.org/blog/2022/01/24/strongswan-vulnerability-%28cve-2021-45079%29.html • CWE-476: NULL Pointer Dereference •

AIDE before 0.17.4 allows local users to obtain root privileges via crafted file metadata (such as XFS extended attributes or tmpfs ACLs), because of a heap-based buffer overflow. AIDE versiones anteriores a 0.17.4, permite a usuarios locales obtener privilegios de root por medio de metadatos de archivo diseñados (como atributos extendidos de XFS o ACLs de tmpfs), debido a un desbordamiento de búfer en la región heap de la memoria A heap-based buffer overflow vulnerability in the base64 functions of AIDE, an advanced intrusion detection system. An attacker could crash the program and possibly execute arbitrary code through large (<16k) extended file attributes or ACL. • http://www.openwall.com/lists/oss-security/2022/01/20/3 https://lists.debian.org/debian-lts-announce/2022/01/msg00024.html https://security.gentoo.org/glsa/202311-07 https://www.debian.org/security/2022/dsa-5051 https://www.ipi.fi/pipermail/aide/2022-January/001713.html https://www.openwall.com/lists/oss-security/2022/01/20/3 https://access.redhat.com/security/cve/CVE-2021-45417 https://bugzilla.redhat.com/show_bug.cgi?id=2041489 • CWE-787: Out-of-bounds Write •

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') •
