CVSS: 9.9EPSS: 18%CPEs: 42EXPL: 3CVE-2021-44142 – Samba fruit_pwrite Heap-based Buffer Overflow Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2021-44142
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 •

https://notcve.org/view.php?id=CVE-2021-4154
A use-after-free flaw was found in cgroup1_parse_param in kernel/cgroup/cgroup-v1.c in the Linux kernel's cgroup v1 parser. A local attacker with a user privilege could cause a privilege escalation by exploiting the fsconfig syscall parameter leading to a container breakout and a denial of service on the system. Se encontró un defecto de uso de memoria previamente liberada en la función cgroup1_parse_param en el archivo kernel/cgroup/cgroup-v1.c en el analizador cgroup v1 del kernel de Linux. Un atacante local con un privilegio de usuario podría causar una escalada de privilegios al explotar el parámetro de syscall fsconfig, conllevando a una ruptura del contenedor y una denegación de servicio en el sistema • https://github.com/Markakd/CVE-2021-4154 https://github.com/veritas501/CVE-2021-4154 https://bugzilla.redhat.com/show_bug.cgi?id=2034514 https://cloud.google.com/anthos/clusters/docs/security-bulletins#gcp-2022-002 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=3b0462726e7ef281c35a7a4ae33e93ee2bc9975b https://security.netapp.com/advisory/ntap-20220225-0004 https://access.redhat.com/security/cve/CVE-2021-4154 • CWE-416: Use After Free •

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.
