https://notcve.org/view.php?id=CVE-2009-1338
The kill_something_info function in kernel/signal.c in the Linux kernel before 2.6.28 does not consider PID namespaces when processing signals directed to PID -1, which allows local users to bypass the intended namespace isolation, and send arbitrary signals to all processes in all namespaces, via a kill command. La función kill_something_info function en kernel/signal.c en el núcleo de Linux versiones anteriores a v2.6.28 no considera namespaces PID cuando está procesando señales dirigidas a PID -1, lo cual permite a atacantes remotos evitar namespace aislados, y envía señales de su elección a todos los procesos en todos los namespaces, a través del comando kill. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=d25141a818383b3c3b09f065698c544a7a0ec6e7 http://lkml.org/lkml/2008/7/23/148 http://secunia.com/advisories/34981 http://secunia.com/advisories/35120 http://secunia.com/advisories/35121 http://secunia.com/advisories/35343 http://secunia.com/advisories/35656 http://wiki.rpath.com/Advisories:rPSA-2009-0084 http://www.debian.org/security/2009/dsa-1787 http://www.debian.org/security/2009/dsa-1800 • CWE-264: Permissions, Privileges, and Access Controls •

https://notcve.org/view.php?id=CVE-2009-1337
The exit_notify function in kernel/exit.c in the Linux kernel before 2.6.30-rc1 does not restrict exit signals when the CAP_KILL capability is held, which allows local users to send an arbitrary signal to a process by running a program that modifies the exit_signal field and then uses an exec system call to launch a setuid application. La función exit_notify en kernel/exit.c en el kernel Linux antes de la versión 2.6.30-rc1 no restringe las señales de salida cuando se alcanza la capacidad CAP_KILL , lo que permite a usuarios locales enviar una señal de su elección a un proceso mediante la ejecución de un programa que modifica el campo exit_signal y, a continuación, utiliza una llamada exec al sistema para iniciar una aplicación setuid. • https://www.exploit-db.com/exploits/8369 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=432870dab85a2f69dc417022646cb9a70acf7f94 http://lists.opensuse.org/opensuse-security-announce/2009-05/msg00002.html http://lists.opensuse.org/opensuse-security-announce/2009-06/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2009-06/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2009-06/msg00002.html http://marc.info/?l=linux-kernel&m=12356 • CWE-264: Permissions, Privileges, and Access Controls •

Integer overflow in rose_sendmsg (sys/net/af_rose.c) in the Linux kernel 2.6.24.4, and other versions before 2.6.30-rc1, might allow remote attackers to obtain sensitive information via a large length value, which causes "garbage" memory to be sent.

The vmx_set_msr function in arch/x86/kvm/vmx.c in the VMX implementation in the KVM subsystem in the Linux kernel before 2.6.29.1 on the i386 platform allows guest OS users to cause a denial of service (OOPS) by setting the EFER_LME (aka "Long mode enable") bit in the Extended Feature Enable Register (EFER) model-specific register, which is specific to the x86_64 platform. La función vmx_set_msr en arch/x86/kvm/vmx.c en la implementación VMX en el subsistema KVM en el kernel de Linux anteriores a v2.6.29.1 en la plataforma i386 permite a los usuarios invitados del SO causar una denegación de servicio (OOPS) estableciendo el bit EFER_LME (también conocido como "modo largo habilitado") en la Extended Feature Enable Register (EFER) registro específico de modelo, lo que es específico para la plataforma x86_64. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=16175a796d061833aacfbd9672235f2d2725df65 http://lists.opensuse.org/opensuse-security-announce/2009-06/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2009-06/msg00002.html http://openwall.com/lists/oss-security/2009/04/01/3 http://patchwork.kernel.org/patch/15549 http://secunia.com/advisories/34478 http://secunia.com/advisories/34981 http://secunia.com/advisories/35120 http://secunia.com • CWE-20: Improper Input Validation •
