CVE-2017-7895 – kernel: NFSv3 server does not properly handle payload bounds checking of WRITE requests
https://notcve.org/view.php?id=CVE-2017-7895
The NFSv2 and NFSv3 server implementations in the Linux kernel through 4.10.13 lack certain checks for the end of a buffer, which allows remote attackers to trigger pointer-arithmetic errors or possibly have unspecified other impact via crafted requests, related to fs/nfsd/nfs3xdr.c and fs/nfsd/nfsxdr.c. Las implementaciones de los servidores NFSv2 y NFSv3 en versiones del kernel de Linux 4.10.13 y anteriores, no realizan ciertas comprobaciones de la parte final de un búfer lo que permitiría a atacantes remotos desencadenar errores de aritmética de punteros o provocar otro impacto inespecífico a través de peticiones especialmente diseñadas. Relacionado con fs/nfsd/nfs3xdr.c y fs/nfsd/nfsxdr.c. The NFSv2 and NFSv3 server implementations in the Linux kernel through 4.10.13 lacked certain checks for the end of a buffer.

CVE-2010-5329
https://notcve.org/view.php?id=CVE-2010-5329
The video_usercopy function in drivers/media/video/v4l2-ioctl.c in the Linux kernel before 2.6.39 relies on the count value of a v4l2_ext_controls data structure to determine a kmalloc size, which might allow local users to cause a denial of service (memory consumption) via a large value. La función video_usercopy en drivers/media/video/v4l2-ioctl.c en el kernel de Linux en versiones anteriores a 2.6.39 se basa en el valor de conteo de una estructura de datos v4l2_ext_controls para determinar un tamaño de kmalloc, lo que podría permitir a usuarios locales causar una denegación de servicio (consumo de memoria) a través de un gran valor. • http://linuxtv.org/irc/v4l/index.php?date=2010-07-29 http://www.openwall.com/lists/oss-security/2015/02/08/4 http://www.securityfocus.com/bid/97986 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=fc0a80798576f80ca10b3f6c9c7097f12fd1d64e https://github.com/torvalds/linux/commit/fc0a80798576f80ca10b3f6c9c7097f12fd1d64e • CWE-399: Resource Management Errors •
CVE-2010-5321
https://notcve.org/view.php?id=CVE-2010-5321
Memory leak in drivers/media/video/videobuf-core.c in the videobuf subsystem in the Linux kernel 2.6.x through 4.x allows local users to cause a denial of service (memory consumption) by leveraging /dev/video access for a series of mmap calls that require new allocations, a different vulnerability than CVE-2007-6761. NOTE: as of 2016-06-18, this affects only 11 drivers that have not been updated to use videobuf2 instead of videobuf. La pérdida de memoria en drivers/media/video/videobuf-core.c en el subsistema videobuf en el kernel de Linux 2.6.x hasta la versión 4.x permite a usuarios locales causar una denegación de servicio (consumo de memoria) aprovechando el acceso /dev/video para una serie de llamadas mmap que requieren nuevas asignaciones, una vulnerabilidad diferente a CVE-2007-6761. NOTA: a partir de 18-06-2016, esto afecta sólo a 11 controladores que no se han actualizado para utilizar videobuf2 en lugar de videobuf. • http://linuxtv.org/irc/v4l/index.php?date=2010-07-29 http://www.openwall.com/lists/oss-security/2015/02/08/4 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=827340 https://bugzilla.kernel.org/show_bug.cgi?id=120571 https://bugzilla.redhat.com/show_bug.cgi?id=620629 • CWE-772: Missing Release of Resource after Effective Lifetime •
CVE-2007-6761
https://notcve.org/view.php?id=CVE-2007-6761
drivers/media/video/videobuf-vmalloc.c in the Linux kernel before 2.6.24 does not initialize videobuf_mapping data structures, which allows local users to trigger an incorrect count value and videobuf leak via unspecified vectors, a different vulnerability than CVE-2010-5321. drivers/media/video/videobuf-vmalloc.c en el kernel de Linux en versiones anteriores a 2.6.24 no inicializa las estructuras de datos videobuf_mapping, lo que permite a usuarios locales desencadenar un valor de recuento incorrecto y una filtración de videobuf a través de vectores no especificados, una vulnerabilidad diferente a CVE-2010 -5321. • http://www.linuxgrill.com/anonymous/kernel/v2.6/ChangeLog-2.6.24 http://www.securityfocus.com/bid/98001 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=827340 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=0b29669c065f60501e7289e1950fa2a618962358 https://github.com/torvalds/linux/commit/0b29669c065f60501e7289e1950fa2a618962358 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVE-2017-7645 – kernel: nfsd: Incorrect handling of long RPC replies
https://notcve.org/view.php?id=CVE-2017-7645
The NFSv2/NFSv3 server in the nfsd subsystem in the Linux kernel through 4.10.11 allows remote attackers to cause a denial of service (system crash) via a long RPC reply, related to net/sunrpc/svc.c, fs/nfsd/nfs3xdr.c, and fs/nfsd/nfsxdr.c. El servidor NFSv2/NFSv3 en el subsistema nfsd en el Kernel de Linux hasta la versión 4.10.11 permite a atacantes remotos provocar una denegación de servicio (caída de sistema) a través de una respuesta RPC larga, relacionada con net/sunrpc/svc.c, fs/nfsd/nfs3xdr.c y fs/nfsd/nfsxdr.c. The NFS2/3 RPC client could send long arguments to the NFS server. These encoded arguments are stored in an array of memory pages, and accessed using pointer variables. Arbitrarily long arguments could make these pointers point outside the array and cause an out-of-bounds memory access. • http://www.debian.org/security/2017/dsa-3886 http://www.securityfocus.com/bid/97950 https://access.redhat.com/errata/RHSA-2017:1615 https://access.redhat.com/errata/RHSA-2017:1616 https://access.redhat.com/errata/RHSA-2017:1647 https://access.redhat.com/errata/RHSA-2018:1319 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=e6838a29ecb484c97e4efef9429643b9851fba6e https://github.com/torvalds/linux/commit/e6838a29ecb484c97e4efef9429643b9851fba6e https://help.ecostruxur • CWE-20: Improper Input Validation CWE-130: Improper Handling of Length Parameter Inconsistency •
