https://notcve.org/view.php?id=CVE-2016-2854
The aufs module for the Linux kernel 3.x and 4.x does not properly maintain POSIX ACL xattr data, which allows local users to gain privileges by leveraging a group-writable setgid directory. El módulo aufs para el kernel de Linux 3.x y 4.x no mantiene correctamente datos POSIX ACL xattr, lo que permite a usuarios locales obtener privilegos aprovechando un directorio con permiso de escritura de grupo setgid. AUFS (Ubuntu 15.10) suffers from an allow_userns fuse/xattr user namespaces privilege escalation vulnerability. • https://www.exploit-db.com/exploits/41761 http://www.halfdog.net/Security/2016/AufsPrivilegeEscalationInUserNamespaces http://www.openwall.com/lists/oss-security/2016/02/24/9 http://www.securityfocus.com/bid/96838 https://sourceforge.net/p/aufs/mailman/message/34864744 • CWE-269: Improper Privilege Management •
CVSS: 4.9EPSS: 0%CPEs: 1EXPL: 0CVE-2016-2053 – kernel: Kernel panic and system lockup by triggering BUG_ON() in public_key_verify_signature()
https://notcve.org/view.php?id=CVE-2016-2053
The asn1_ber_decoder function in lib/asn1_decoder.c in the Linux kernel before 4.3 allows attackers to cause a denial of service (panic) via an ASN.1 BER file that lacks a public key, leading to mishandling by the public_key_verify_signature function in crypto/asymmetric_keys/public_key.c. La función asn1_ber_decoder en lib/asn1_decoder.c en el kernel de Linux en versiones anteriores a 4.3 permite a atacantes provocar una denegación de servicio (pánico) a través de un archivo ASN.1 BER que carece de clave pública, llevando a un manejo incorrecto por la función public_key_verify_signature en crypto/asymmetric_keys/public_key.c. A syntax vulnerability was discovered in the kernel's ASN1.1 DER decoder, which could lead to memory corruption or a complete local denial of service through x509 certificate DER files. A local system user could use a specially created key file to trigger BUG_ON() in the public_key_verify_signature() function (crypto/asymmetric_keys/public_key.c), to cause a kernel panic and crash the system. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=0d62e9dd6da45bbf0f33a8617afc5fe774c8f45f http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00044.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00052.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00054.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00003.html http://lists.opensuse.org • CWE-228: Improper Handling of Syntactically Invalid Structure CWE-310: Cryptographic Issues •

La función ims_pcu_parse_cdc_data en drivers/input/misc/ims-pcu.c en el kernel de Linux en versiones anteriores a 4.5.1 permite a atacantes físicamente próximos provocar una denegación de servicio (caída de sistema) a través de un dispositivo USB sin interfaz para un maestro y un esclavo. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=a0ad220c96692eda76b2e3fd7279f3dcd1d8a8ff http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00060.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00054.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00056.html http://lists.opensuse.org/opensuse-security-announce/2016-07/msg00005.html http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.5.1 http://www.openwall.com/l •

The atl2_probe function in drivers/net/ethernet/atheros/atlx/atl2.c in the Linux kernel through 4.5.2 incorrectly enables scatter/gather I/O, which allows remote attackers to obtain sensitive information from kernel memory by reading packet data. La función atl2_probe en drivers/net/ethernet/atheros/atlx/atl2.c en el kernel de Linux hasta la versión 4.5.2 activa incorrectamente scatter/gather I/O, lo que permite a atacantes remotos obtener información sensible de la memoria del kernel leyendo datos de paquete. It was discovered that the atl2_probe() function in the Atheros L2 Ethernet driver in the Linux kernel incorrectly enabled scatter/gather I/O. A remote attacker could use this flaw to obtain potentially sensitive information from the kernel memory. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f43bfaeddc79effbf3d0fcb53ca477cca66f3db8 http://rhn.redhat.com/errata/RHSA-2016-2574.html http://rhn.redhat.com/errata/RHSA-2016-2584.html http://www.debian.org/security/2016/dsa-3607 http://www.openwall.com/lists/oss-security/2016/03/16/7 http://www.oracle.com/technetwork/topics/security/linuxbulletinjul2016-3090544.html http://www.oracle.com/technetwork/topics/security/ovmbulletinjul2016-3090546.html http://www.secu • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVSS: 5.1EPSS: 0%CPEs: 10EXPL: 0CVE-2015-8839 – kernel: ext4 filesystem page fault race condition with fallocate call.
https://notcve.org/view.php?id=CVE-2015-8839
Multiple race conditions in the ext4 filesystem implementation in the Linux kernel before 4.5 allow local users to cause a denial of service (disk corruption) by writing to a page that is associated with a different user's file after unsynchronized hole punching and page-fault handling. Múltiples condiciones de carrera en la implementación del sistema de archivos ext4 en el kernel de Linux en versiones anteriores a 4.5 permite a usuarios locales provocar una denegación de servicio (corrupción de disco) escribiendo a una página que está asociada con un archivo de usuario diferente después del manejo de hole punching desincronizado y de fallo de página. A flaw was found in the Linux kernel when attempting to "punch a hole" in files existing on an ext4 filesystem. When punching holes into a file races with the page fault of the same area, it is possible that freed blocks remain referenced from page cache pages mapped to process' address space. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=ea3d7209ca01da209cda6f0dea8be9cc4b7a933b http://www.openwall.com/lists/oss-security/2016/04/01/4 http://www.securityfocus.com/bid/85798 http://www.securitytracker.com/id/1035455 http://www.ubuntu.com/usn/USN-3005-1 http://www.ubuntu.com/usn/USN-3006-1 http://www.ubuntu.com/usn/USN-3007-1 https://access.redhat.com/errata/RHSA-2017:1842 https://access.redhat.com/errata/RHSA-2017:2077 https:& • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
