https://notcve.org/view.php?id=CVE-2021-45868
In the Linux kernel before 5.15.3, fs/quota/quota_tree.c does not validate the block number in the quota tree (on disk). This can, for example, lead to a kernel/locking/rwsem.c use-after-free if there is a corrupted quota file. En el kernel de Linux versiones anteriores a 5.15.3, el archivo fs/quota/quota_tree.c no comprueba el número de bloque en el árbol de cuotas (en disco). Esto puede, por ejemplo, conllevar a un uso de memoria previamente liberada del archivo kernel/locking/rwsem.c si se presenta un archivo de cuotas corrupto • https://bugzilla.kernel.org/show_bug.cgi?id=214655 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.15.3 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=9bf3d20331295b1ecb81f4ed9ef358c51699a050 https://security.netapp.com/advisory/ntap-20220419-0003 https://www.openwall.com/lists/oss-security/2022/03/17/1 https://www.openwall.com/lists/oss-security/2022/03/17/2 • CWE-416: Use After Free •
CVSS: 7.8EPSS: 0%CPEs: 54EXPL: 1CVE-2022-1011 – kernel: FUSE allows UAF reads of write() buffers, allowing theft of (partial) /etc/shadow hashes
https://notcve.org/view.php?id=CVE-2022-1011
A use-after-free flaw was found in the Linux kernel’s FUSE filesystem in the way a user triggers write(). This flaw allows a local user to gain unauthorized access to data from the FUSE filesystem, resulting in privilege escalation. Se ha encontrado un fallo de uso después de libre en el sistema de archivos FUSE del kernel de Linux en la forma en que un usuario activa write(). Este defecto permite a un usuario local obtener acceso no autorizado a los datos del sistema de archivos FUSE, lo que resulta en una escalada de privilegios Linux suffers from a vulnerability where FUSE allows use-after-free reads of write() buffers, allowing theft of (partial) /etc/shadow hashes. • https://github.com/xkaneiki/CVE-2022-1011 https://bugzilla.redhat.com/show_bug.cgi?id=2064855 https://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse.git/commit/?h=for-next https://lists.debian.org/debian-lts-announce/2022/07/msg00000.html https://www.debian.org/security/2022/dsa-5173 https://www.oracle.com/security-alerts/cpujul2022.html https://access.redhat.com/security/cve/CVE-2022-1011 • CWE-416: Use After Free •
CVSS: 6.8EPSS: 0%CPEs: 166EXPL: 0CVE-2021-25220 – DNS forwarders - cache poisoning vulnerability

BIND 9.11.0 -> 9.11.36 9.12.0 -> 9.16.26 9.17.0 -> 9.18.0 BIND Supported Preview Editions: 9.11.4-S1 -> 9.11.36-S1 9.16.8-S1 -> 9.16.26-S1 Versions of BIND 9 earlier than those shown - back to 9.1.0, including Supported Preview Editions - are also believed to be affected but have not been tested as they are EOL. The cache could become poisoned with incorrect records leading to queries being made to the wrong servers, which might also result in false information being returned to clients. BIND versiones 9.11.0 posteriores a 9.11.36, versiones 9.12.0 posteriores a 9.16.26, versiones 9.17.0 posteriores a 9.18.0, Ediciones Preliminares Soportadas con BIND: versiones .11.4-S1 posteriores a 9.11.36-S1, versiones 9.16.8-S1 posteriores a 9.16.26-S1, también creemos que las versiones de BIND 9 anteriores a las mostradas - hasta la versión 9.1.0, incluyendo las ediciones preliminares soportadas - también están afectadas pero no han sido probadas ya que son EOL. La caché podría envenenarse con registros incorrectos, conllevando a una realización de consultas a servidores erróneos, lo que también podría resultar en que se devolviera información falsa a clientes A cache poisoning vulnerability was found in BIND when using forwarders. Bogus NS records supplied by the forwarders may be cached and used by name if it needs to recurse for any reason. • https://cert-portal.siemens.com/productcert/pdf/ssa-637483.pdf https://kb.isc.org/v1/docs/cve-2021-25220 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/2SXT7247QTKNBQ67MNRGZD23ADXU6E5U https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/5VX3I2U3ICOIEI5Y7OYA6CHOLFMNH3YQ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/API7U5E7SX7BAAVFNW366FFJGD6NZZKV https://lists.fedoraproject.org/archives/list/package-announc • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •

Specifically crafted TCP streams can cause connections to BIND to remain in CLOSE_WAIT status for an indefinite period of time, even after the client has terminated the connection. BIND versiones 9.16.11 posteriores a 9.16.26, versiones 9.17.0 posteriores a 9.18.0 y versiones 9.16.11-S1 posteriores a 9.16.26-S1 de BIND Supported Preview Edition. Los flujos TCP específicamente diseñados pueden causar que las conexiones a BIND permanezcan en estado CLOSE_WAIT durante un período de tiempo indefinido, incluso después de que el cliente haya terminado la conexión A flaw was found in Bind that incorrectly handles certain crafted TCP streams. The vulnerability allows TCP connection slots to be consumed for an indefinite time frame via a specifically crafted TCP stream sent from a client. • https://cert-portal.siemens.com/productcert/pdf/ssa-637483.pdf https://kb.isc.org/v1/docs/cve-2022-0396 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/NYD7US4HZRFUGAJ66ZTHFBYVP5N3OQBY https://security.gentoo.org/glsa/202210-25 https://security.netapp.com/advisory/ntap-20220408-0001 https://access.redhat.com/security/cve/CVE-2022-0396 https://bugzilla.redhat.com/show_bug.cgi?id=2064513 • CWE-404: Improper Resource Shutdown or Release CWE-459: Incomplete Cleanup •
