Multiple race conditions in the Advanced Union Filesystem (aufs) aufs3-mmap.patch and aufs4-mmap.patch patches for the Linux kernel 3.x and 4.x allow local users to cause a denial of service (use-after-free and BUG) or possibly gain privileges via a (1) madvise or (2) msync system call, related to mm/madvise.c and mm/msync.c. Múltiples condiciones de carrera en los parches de Advanced Union Filesystem (aufs) aufs3-mmap.patch y aufs4-mmap.patch para el kernel Linux 3.x y 4.x permite a usuarios locales causar una denegación de servicio (uso después de liberación de memoria y BUG) o posiblemente obtener privilegios a través de una llamada al sistema (1) madvise o (2) msync, relacionada con mm/madvise.c y mm/msync.c. • http://sourceforge.net/p/aufs/mailman/message/34449209 http://www.debian.org/security/2015/dsa-3364 http://www.openwall.com/lists/oss-security/2015/09/22/10 http://www.ubuntu.com/usn/USN-2777-1 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •

Kernel Samepage Merging (KSM) in the Linux kernel 2.6.32 through 4.x does not prevent use of a write-timing side channel, which allows guest OS users to defeat the ASLR protection mechanism on other guest OS instances via a Cross-VM ASL INtrospection (CAIN) attack. NOTE: the vendor states "Basically if you care about this attack vector, disable deduplication." Share-until-written approaches for memory conservation among mutually untrusting tenants are inherently detectable for information disclosure, and can be classified as potentially misunderstood behaviors rather than vulnerabilities ** DISPUTADA ** Kernel Samepage Merging (KSM) en el kernel de Linux 2.6.32 hasta la versión 4.x no previene el uso de un canal lateral de sincronización de escritura, lo que permite a usuarios invitados del SO derrotar el mecanismo de protección de ASLR en otras instancias invitadas del SO a través de un ataque Cross-VM ASL INtrospection (CAIN). NOTA: el vendedor afirma "Básicamente si te preocupa este vector de ataque, inhabilita la deduplicación". Enfoques de compartir hasta escritura para conservación de memoria entre inquilinos mutuamente desconfiados son inherentemente detectables para divulgación de información y pueden clasificarse como comportamientos potencialmente malinterpretados en lugar de vulnerabilidades. • http://www.antoniobarresi.com/files/cain_advisory.txt http://www.kb.cert.org/vuls/id/935424 http://www.securityfocus.com/bid/76256 https://bugzilla.redhat.com/show_bug.cgi?id=1252096 https://www.kb.cert.org/vuls/id/BGAR-A2CNKG https://www.kb.cert.org/vuls/id/BLUU-9ZAHZH https://www.usenix.org/system/files/conference/woot15/woot15-paper-barresi.pdf • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVSS: 7.2EPSS: 0%CPEs: 15EXPL: 0CVE-2014-0069 – kernel: cifs: incorrect handling of bogus user pointers during uncached writes
https://notcve.org/view.php?id=CVE-2014-0069
The cifs_iovec_write function in fs/cifs/file.c in the Linux kernel through 3.13.5 does not properly handle uncached write operations that copy fewer than the requested number of bytes, which allows local users to obtain sensitive information from kernel memory, cause a denial of service (memory corruption and system crash), or possibly gain privileges via a writev system call with a crafted pointer. La función cifs_iovec_write en fs/cifs/file.c en el kernel de Linux hasta 3.13.5 no maneja debidamente operaciones de escritura no en caché que copian menos bytes de los solicitados, lo que permite a usuarios locales obtener información sensible de la memoria del kernel, causar una denegación de servicio (corrupción de memoria y caída del sistema) o posiblemente ganar privilegios a través de una llamada al sistema writev con un puntero manipulado. • http://article.gmane.org/gmane.linux.kernel.cifs/9401 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=5d81de8e8667da7135d3a32a964087c0faf5483f http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00026.html http://rhn.redhat.com/errata/RHSA-2014-0328.html http://www.openwall.com/lists/oss-security/2014/02/17/4 http://www.securityfocus.com/bid/65588 https://bugzilla.redhat.com/show_bug.cgi?id=1064253 https://github.com/torvalds/linux/comm • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
