https://notcve.org/view.php?id=CVE-2012-3364
Multiple stack-based buffer overflows in the Near Field Communication Controller Interface (NCI) in the Linux kernel before 3.4.5 allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via incoming frames with crafted length fields. Múltiples desbordamientos de búfer basados en pila en Near Field Communication Controller Interface (NCI) en el kernel de Linux antes de v3.4.5 permite a atacantes remotos provocar una denegación de servicio (caída) y posiblemente ejecutar código arbitrario a través de tramas de entrada con campos de longitud hechas a mano. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=67de956ff5dc1d4f321e16cfbd63f5be3b691b43 http://marc.info/?l=linux-kernel&m=134030878917784&w=2 http://ubuntu.com/usn/usn-1529-1 http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.4.5 http://www.openwall.com/lists/oss-security/2012/06/27/9 https://github.com/torvalds/linux/commit/67de956ff5dc1d4f321e16cfbd63f5be3b691b43 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVE-2012-2745 – kernel: cred: copy_process() should clear child->replacement_session_keyring
https://notcve.org/view.php?id=CVE-2012-2745
The copy_creds function in kernel/cred.c in the Linux kernel before 3.3.2 provides an invalid replacement session keyring to a child process, which allows local users to cause a denial of service (panic) via a crafted application that uses the fork system call.

CVE-2012-2744 – kernel: netfilter: null pointer dereference in nf_ct_frag6_reasm()

net/ipv6/netfilter/nf_conntrack_reasm.c in the Linux kernel before 2.6.34, when the nf_conntrack_ipv6 module is enabled, allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) via certain types of fragmented IPv6 packets. net/ipv6/netfilter/nf_conntrack_reasm.c en el kernel de Linux anterior a v2.6.34, cuando el módulo nf_conntrack_ipv6 está habilitado, permite a atacantes remotos causar una denegación de servicio (referencia de puntero a NULL y caída del sistema) mediante ciertos tipos de paquetes IPv6 fragmentados. • http://ftp.osuosl.org/pub/linux/kernel/v2.6/ChangeLog-2.6.34 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=9e2dcf72023d1447f09c47d77c99b0c49659e5ce http://rhn.redhat.com/errata/RHSA-2012-1064.html http://rhn.redhat.com/errata/RHSA-2012-1148.html http://secunia.com/advisories/49928 http://www.securityfocus.com/bid/54367 http://www.securitytracker.com/id?1027235 https://bugzilla.redhat.com/show_bug.cgi?id=833402 https://github.com/torvalds • CWE-476: NULL Pointer Dereference •
CVE-2012-3375 – Linux Kernel 3.2.24 - 'fs/eventpoll.c' Local Denial of Service
https://notcve.org/view.php?id=CVE-2012-3375
The epoll_ctl system call in fs/eventpoll.c in the Linux kernel before 3.2.24 does not properly handle ELOOP errors in EPOLL_CTL_ADD operations, which allows local users to cause a denial of service (file-descriptor consumption and system crash) via a crafted application that attempts to create a circular epoll dependency. NOTE: this vulnerability exists because of an incorrect fix for CVE-2011-1083. La llamada al sistema epoll_ctl en fs/eventpoll.c en el Kernel de Linux anteriores a v3.2.24 no gestiona de forma adecuada errores ELOOP en operaciones EPOLL_CTL_ADD, lo que permite a usuarios locales provocar una denegación de servicio (consumo de descriptores de ficheros y caída del sistema) a través de una aplicación manipulada que intenta crear una dependencia epoll circular. NOTA: esta vulnerabilidad existe debido a una resolución incorrecta de CVE-2011-1083. The Linux kernel suffers from a local denial of service vulnerability in fs/eventpoll.c. • https://www.exploit-db.com/exploits/19605 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=13d518074a952d33d47c428419693f63389547e9 http://secunia.com/advisories/51164 http://ubuntu.com/usn/usn-1529-1 http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.2.24 http://www.openwall.com/lists/oss-security/2012/07/04/2 http://www.securitytracker.com/id?1027237 https://bugzilla.redhat.com/show_bug.cgi?id=837502 https://downloads.avaya.com& •

fs/proc/root.c in the procfs implementation in the Linux kernel before 3.2 does not properly interact with CLONE_NEWPID clone system calls, which allows remote attackers to cause a denial of service (reference leak and memory consumption) by making many connections to a daemon that uses PID namespaces to isolate clients, as demonstrated by vsftpd. fs/proc/root.c en las implementaciones de procfs del kernel de Linux anteriores a v3.2 no interactua adecuadamente con las llamadas al sistema de CLONE_NEWPID, lo que permite a atacantes remotos provocar una denegación de servicio (pérdida de referencia y consumo excesivo de memoria), haciendo muchas conexiones a un demonio que usa namespaces PID para aislar a los clientes, como lo demuestra vsftpd. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=905ad269c55fc62bee3da29f7b1d1efeba8aa1e1 http://ubuntu.com/usn/usn-1607-1 http://www.kernel.org/pub/linux/kernel/v3.x http://www.kernel.org/pub/linux/kernel/v3.x/patch-3.2.bz2 http://www.openwall.com/lists/oss-security/2012/04/20/25 http://www.openwall.com/lists/oss-security/2012/04/22/1 http://www.securityfocus.com/bid/55774 http://www.ubuntu.com/usn/USN-1594-1 https:& • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
