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 •

The collect_mounts function in fs/namespace.c in the Linux kernel before 4.0.5 does not properly consider that it may execute after a path has been unmounted, which allows local users to cause a denial of service (system crash) by leveraging user-namespace root access for an MNT_DETACH umount2 system call. La función collect_mounts en fs/namespace.c en el kernel de Linux en versiones anteriores a 4.0.5 no considera correctamente que se pueda ejecutar después de que una ruta sea desmontada, lo que permite a usuarios locales provocar una denegación de servicio (caída de sistema) aprovechando acceso root al espacio de nombres de usuario para una llamada de sistema MNT_DETACH umount2. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=cd4a40174b71acd021877341684d8bb1dc8ea4ae http://openwall.com/lists/oss-security/2015/05/29/10 http://openwall.com/lists/oss-security/2015/05/29/5 http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.0.5 http://www.openwall.com/lists/oss-security/2015/06/04/5 https://bugzilla.redhat.com/show_bug.cgi?id=1248486 https://github.com/torvalds/linux/commit/cd4a40174b71acd021877341684d8bb1dc8ea4ae •

The gtco_probe function in drivers/input/tablet/gtco.c in the Linux kernel through 4.5.2 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted endpoints value in a USB device descriptor. La función gtco_probe en drivers/input/tablet/gtco.c en el kernel de Linux hasta la versión 4.5.2 permite a atacantes físicamente próximos provocar una denegación de servicio (referencia a puntero NULL y caída de sistema) a través de un valor de dispositivos finales manipulado en un descriptor de dispositivo USB. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=162f98dea487206d9ab79fc12ed64700667a894d http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00052.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00007.html http://www.debian.org/security/2016/dsa-3607 http://www.securityfocus.com/bid/85425 http://www.ubuntu.com/usn/USN-2989-1 http://www.ubuntu.com/usn/USN-2996-1 http://www.ubuntu.com/usn/USN-2997-1 http://www.ubuntu •

fs/namespace.c in the Linux kernel before 4.0.2 processes MNT_DETACH umount2 system calls without verifying that the MNT_LOCKED flag is unset, which allows local users to bypass intended access restrictions and navigate to filesystem locations beneath a mount by calling umount2 within a user namespace. fs/namespace.c en el kernel de Linux en versiones anteriores a 4.0.2 procesa llamadas de sistema MNT_DETACH umount2 sin verificar que el indicador MNT_LOCKED no está establecido, lo que permite a usuarios locales eludir restricciones dedicadas al acceso y navegar a localizaciones de archivos de sistema bajo un montaje llamando a umount2 en un espacio de nombres de usuario. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=ce07d891a0891d3c0d0c2d73d577490486b809e1 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/2016-08/msg00000.html http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.0.2 http://www.openwall.com/lists/oss-security/2015/04/17/4 http://www.securityfocus.com/bid/742 • CWE-284: Improper Access Control •
