CVSS: 5.0EPSS: 1%CPEs: 1EXPL: 2CVE-2015-1593 – kernel: Linux stack ASLR implementation Integer overflow
https://notcve.org/view.php?id=CVE-2015-1593
The stack randomization feature in the Linux kernel before 3.19.1 on 64-bit platforms uses incorrect data types for the results of bitwise left-shift operations, which makes it easier for attackers to bypass the ASLR protection mechanism by predicting the address of the top of the stack, related to the randomize_stack_top function in fs/binfmt_elf.c and the stack_maxrandom_size function in arch/x86/mm/mmap.c. La característica de aleatoriedad de la pila en el Kernel de Linux anterior a 3.19.1 en plataformas de 64-bits utiliza un tipo de datos incorrecto por el resultado de operaciones de bitwise left-shift, lo que hace que sea más fácil para atacantes evadir el mecanismo de protección ASLR prediciendo direcciones del tope de la pila, relacionado con la función andomize_stack_top en fs/binfmt_elf.c y la función stack_maxrandom_size en arch/x86/mm/mmap.c. An integer overflow flaw was found in the way the Linux kernel randomized the stack for processes on certain 64-bit architecture systems, such as x86-64, causing the stack entropy to be reduced by four. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=4e7c22d447bb6d7e37bfe39ff658486ae78e8d77 http://hmarco.org/bugs/linux-ASLR-integer-overflow.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00015.html http://rhn.redhat.com/errata/RHSA-2015-1137.html http://rhn.redhat.com/errata/RHSA-2015-1138.html http://rhn.redhat.com/errata/RHSA-2015-1221.html http://www.debi • CWE-190: Integer Overflow or Wraparound CWE-264: Permissions, Privileges, and Access Controls •

The parse_rock_ridge_inode_internal function in fs/isofs/rock.c in the Linux kernel before 3.18.2 does not validate a length value in the Extensions Reference (ER) System Use Field, which allows local users to obtain sensitive information from kernel memory via a crafted iso9660 image. La función parse_rock_ridge_inode_internal en fs/isofs/rock.c en el kernel de Linux anterior a 3.18.2 no valida un valor de longitud en el campo Extensions Reference (ER) System Use, lo que permite a usuarios locales obtener información sensible de la memoria del kernel a través de una imagen iso9660 manipulada. An information leak flaw was found in the way the Linux kernel's ISO9660 file system implementation accessed data on an ISO9660 image with RockRidge Extension Reference (ER) records. An attacker with physical access to the system could use this flaw to disclose up to 255 bytes of kernel memory. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=4e2024624e678f0ebb916e6192bd23c1f9fdf696 http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00020.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00025.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00009.html http://lists.o • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2014-9585
The vdso_addr function in arch/x86/vdso/vma.c in the Linux kernel through 3.18.2 does not properly choose memory locations for the vDSO area, which makes it easier for local users to bypass the ASLR protection mechanism by guessing a location at the end of a PMD. La función vdso_addr en arch/x86/vdso/vma.c en el kernel de Linux hasta 3.18.2 no elige correctamente localizaciones de memoria para la área vDSO, lo que facilita a usuarios locales evadir el mecanismo de protección ASLR mediante la adivinación de una localización al final de un PMD. An information leak flaw was found in the way the Linux kernel's Virtual Dynamic Shared Object (vDSO) implementation performed address randomization. A local, unprivileged user could use this flaw to leak kernel memory addresses to user-space. • http://git.kernel.org/?p=linux/kernel/git/luto/linux.git%3Ba=commit%3Bh=bc3b94c31d65e761ddfe150d02932c65971b74e2 http://git.kernel.org/?p=linux/kernel/git/tip/tip.git%3Ba=commit%3Bh=fbe1bf140671619508dfa575d74a185ae53c5dbb http://lists.fedoraproject.org/pipermail/package-announce/2015-January/148480.html http://lists.opensuse.org/opensuse-security-announce/2015-01/msg00035.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg0 •

Race condition in the key_gc_unused_keys function in security/keys/gc.c in the Linux kernel through 3.18.2 allows local users to cause a denial of service (memory corruption or panic) or possibly have unspecified other impact via keyctl commands that trigger access to a key structure member during garbage collection of a key. Condición de carrera en la función key_gc_unused_keys en security/keys/gc.c en el kernel de Linux hasta 3.18.2 permite a usuarios locales causar una denegación de servicio (corrupción de memoria o pánico) o posiblemente tener otro impacto no especificado a través de comandos keyctl que provocan el acceso a un miembro de la estructura clave durante la recogida de basura de una clave. A race condition flaw was found in the way the Linux kernel keys management subsystem performed key garbage collection. A local attacker could attempt accessing a key while it was being garbage collected, which would cause the system to crash. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=a3a8784454692dd72e5d5d34dcdab17b4420e74c http://lists.fedoraproject.org/pipermail/package-announce/2015-January/147864.html http://lists.fedoraproject.org/pipermail/package-announce/2015-January/147973.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00009.html http://rhn.redhat.com/errata/RHSA-2015-0864.html http://rhn.redhat.com/errata/RHSA-2015-1137.html http://rhn.redhat.com/errata/RHSA-2015-1138& • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •

The batadv_frag_merge_packets function in net/batman-adv/fragmentation.c in the B.A.T.M.A.N. implementation in the Linux kernel through 3.18.1 uses an incorrect length field during a calculation of an amount of memory, which allows remote attackers to cause a denial of service (mesh-node system crash) via fragmented packets. La función batadv_frag_merge_packets en net/batman-adv/fragmentation.c en la implementación B.A.T.M.A.N. en el kernel de Linux hasta 3.18.1 utiliza un campo de longitud incorrecto durante un cálculo de una cantidad de memoria, lo que permite a atacantes remotos causar una denegación de servicio (caída del sistema de modo de malla) a través de paquetes fragmentados. • http://bugs.debian.org/774155 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=5b6698b0e4a37053de35cc24ee695b98a7eb712b http://lists.fedoraproject.org/pipermail/package-announce/2015-January/147864.html http://lists.fedoraproject.org/pipermail/package-announce/2015-January/147973.html http://www.mandriva.com/security/advisories?name=MDVSA-2015:058 http://www.openwall.com/lists/oss-security/2014/12/31/7 http://www.spinics.net/lists/netdev/msg309425.html http:// • CWE-399: Resource Management Errors •
