https://notcve.org/view.php?id=CVE-2015-2830
arch/x86/kernel/entry_64.S in the Linux kernel before 3.19.2 does not prevent the TS_COMPAT flag from reaching a user-mode task, which might allow local users to bypass the seccomp or audit protection mechanism via a crafted application that uses the (1) fork or (2) close system call, as demonstrated by an attack against seccomp before 3.16. arch/x86/kernel/entry_64.S en el kernel de Linux anterior a 3.19.2 no impide que el indicador TS_COMPAT llegue a una tarea de modo de usuario, lo que podría permitir a usuarios locales evadir el mecanismo de protección de seccomp o de auditoria a través de una aplicación manipulada que utiliza la llamada de sistema (1) bifurcada o (2) cerrada, tal y como fue demostrado por un ataque sobre seccomp anterior a 3.16. A flaw was found in the way the Linux kernel's 32-bit emulation implementation handled forking or closing of a task with an 'int80' entry. A local user could potentially use this flaw to escalate their privileges on the system. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=956421fbb74c3a6261903f3836c0740187cf038b http://lists.opensuse.org/opensuse-security-announce/2015-09/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2015-09/msg00018.html http://lists.opensuse.org/opensuse-security-announce/2015-09/msg00021.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& • CWE-264: Permissions, Privileges, and Access Controls CWE-393: Return of Wrong Status Code •
CVSS: 5.7EPSS: 0%CPEs: 1EXPL: 0CVE-2014-9715 – kernel: netfilter connection tracking extensions denial of service
https://notcve.org/view.php?id=CVE-2014-9715
include/net/netfilter/nf_conntrack_extend.h in the netfilter subsystem in the Linux kernel before 3.14.5 uses an insufficiently large data type for certain extension data, which allows local users to cause a denial of service (NULL pointer dereference and OOPS) via outbound network traffic that triggers extension loading, as demonstrated by configuring a PPTP tunnel in a NAT environment. include/net/netfilter/nf_conntrack_extend.h en el subsistema netfilter en el kernel de Linux anterior a 3.14.5 utiliza un tipo de datos insuficientemente grande para ciertos datos de extensión, lo que permite a usuarios locales causar una denegación de servicio (referencia a puntero nulo y OOPS) a través de trafico de red saliente que provoca la carga de extensiones, tal y como fue demostrado mediante la configuración de un túnel PPTP en un entorno NAT. An integer overflow flaw was found in the way the Linux kernel's netfilter connection tracking implementation loaded extensions. An attacker on a local network could potentially send a sequence of specially crafted packets that would initiate the loading of a large number of extensions, causing the targeted system in that network to crash. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=223b02d923ecd7c84cf9780bb3686f455d279279 http://marc.info/?l=netfilter-devel&m=140112364215200&w=2 http://rhn.redhat.com/errata/RHSA-2015-1534.html http://rhn.redhat.com/errata/RHSA-2015-1564.html http://www.debian.org/security/2015/dsa-3237 http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.14.5 http://www.openwall.com/lists/oss-security/2015/04/08/1 http://www.oracle.com/te • CWE-841: Improper Enforcement of Behavioral Workflow •
