CVE-2015-0275 – kernel: fs: ext4: fallocate zero range page size > block size BUG()
https://notcve.org/view.php?id=CVE-2015-0275
The ext4_zero_range function in fs/ext4/extents.c in the Linux kernel before 4.1 allows local users to cause a denial of service (BUG) via a crafted fallocate zero-range request. La función ext4_zero_range en fs/ext4/extents.c en el kernel de Linux en versiones anteriores a 4.1 permite a usuarios locales provocar una denegación de servicio (BUG) a través de una petición de rango cero a fallocate manipulada. A flaw was found in the way the Linux kernel's ext4 file system handled the "page size > block size" condition when the fallocate zero range functionality was used. A local attacker could use this flaw to crash the system. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=0f2af21aae11972fa924374ddcf52e88347cf5a8 http://rhn.redhat.com/errata/RHSA-2015-1778.html http://rhn.redhat.com/errata/RHSA-2015-1787.html http://www.openwall.com/lists/oss-security/2015/02/23/14 http://www.oracle.com/technetwork/topics/security/linuxbulletinoct2015-2719645.html http://www.securityfocus.com/bid/75139 http://www.securitytracker.com/id/1034454 http://www.spinics.net/lists/linux-ext4/msg47193.html ht • CWE-17: DEPRECATED: Code •

CVE-2015-1805 – kernel: pipe: iovec overrun leading to memory corruption
https://notcve.org/view.php?id=CVE-2015-1805
The (1) pipe_read and (2) pipe_write implementations in fs/pipe.c in the Linux kernel before 3.16 do not properly consider the side effects of failed __copy_to_user_inatomic and __copy_from_user_inatomic calls, which allows local users to cause a denial of service (system crash) or possibly gain privileges via a crafted application, aka an "I/O vector array overrun." Vulnerabilidad en las implementaciones (1) pipe_read y (2) pipe_write en fs/pipe.c en el kernel de Linux en versiones anteriores a 3.16, no considera correctamente los efectos secundarios de llamadas __copy_to_user_inatomic y __copy_from_user_inatomic fallidas, lo que permite a usuarios locales provocar una denegación de servicio (caída del sistema) o posiblemente obtener privilegios a través de una aplicación manipulada, también conocida como una 'saturación del array del vector I/O'. It was found that the Linux kernel's implementation of vectored pipe read and write functionality did not take into account the I/O vectors that were already processed when retrying after a failed atomic access operation, potentially resulting in memory corruption due to an I/O vector array overrun. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system. • https://github.com/panyu6325/CVE-2015-1805 https://github.com/ireshchaminda1/Android-Privilege-Escalation-Remote-Access-Vulnerability-CVE-2015-1805 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=637b58c2887e5e57850865839cc75f59184b23d1 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f0d1bec9d58d4c038d0ac958c9af82be6eb18045 http://lists.opensuse.org/opensuse-security-announce/2015-07/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2015-07/msg00049.html • CWE-17: DEPRECATED: Code •
CVE-2014-9710
https://notcve.org/view.php?id=CVE-2014-9710
The Btrfs implementation in the Linux kernel before 3.19 does not ensure that the visible xattr state is consistent with a requested replacement, which allows local users to bypass intended ACL settings and gain privileges via standard filesystem operations (1) during an xattr-replacement time window, related to a race condition, or (2) after an xattr-replacement attempt that fails because the data does not fit. La implementación Btrfs en el kernel de Linux anterior a 3.19 no asegura que el estado xattr visible sea consistente con un remplazo solicitado, lo que permite a usuarios locales evadir las configuraciones ACL y ganar privilegios a través de las operaciones del sistema de ficheros estándares (1) durante una ventana de tiempo de remplazo de xattr, relacionado con una condición de carrera o (2) después de intento de remplazo de xattr que falla porque la fecha no encaja. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=5f5bc6b1e2d5a6f827bc860ef2dc5b6f365d1339 http://lists.opensuse.org/opensuse-security-announce/2015-07/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2015-09/msg00009.html http://www.openwall.com/lists/oss-security/2015/03/24/11 http://www.securitytracker.com/id/1032418 https://bugzilla.redhat.com/show_bug.cgi?id=1205079 https://github.com/torvalds/linux/commit/5f5bc6b1e2d5a6f827bc860ef2dc5b6f365d1339 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
