CVE-2009-1961 – Linux Kernel 2.6.x - 'splice' Double Lock Local Denial of Service
https://notcve.org/view.php?id=CVE-2009-1961
The inode double locking code in fs/ocfs2/file.c in the Linux kernel 2.6.30 before 2.6.30-rc3, 2.6.27 before 2.6.27.24, 2.6.29 before 2.6.29.4, and possibly other versions down to 2.6.19 allows local users to cause a denial of service (prevention of file creation and removal) via a series of splice system calls that trigger a deadlock between the generic_file_splice_write, splice_from_pipe, and ocfs2_file_splice_write functions. El código de doble bloqueo del inodo de fs/ocfs2/file.c del kernel de Linux v2.6.30 anterior a v2.6.30-rc3, v2.6.27 anterior a v2.6.27.24, v2.6.29 anterior a v2.6.29.4 y puede que otras versiones anteriores a v2.6.19; permite a usuarios locales provocar una denegación de servicio (prevención de creación y borrado de ficheros) a través de una serie de llamadas al sistema anidadas que provocan un bloqueo mutuo -deadlock- entre las funciones generic_file_splice_write, splice_from_pipe y ocfs2_file_splice_write. • https://www.exploit-db.com/exploits/33015 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commitdiff%3Bh=7bfac9ecf0585962fe13584f5cf526d8c8e76f17 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/2009-07/msg00004.html http://secunia.com/advisories/35390 http://secunia.com/advisories/35394 http://secunia.com/advisories/35656 http • CWE-667: Improper Locking •

Buffer overflow in the util_path_encode function in udev/lib/libudev-util.c in udev before 1.4.1 allows local users to cause a denial of service (service outage) via vectors that trigger a call with crafted arguments. Desbordamiento de búfer en la función util_path_encode en udev/lib/libudev-util.c en udev antes de v1.4.1 permite a usuarios locales provocar una denegación de servicio (parada del servicio) mediante vectores que disparan una llamada con argumentos manipulados. • http://git.kernel.org/?p=linux/hotplug/udev.git%3Ba=commitdiff%3Bh=662c3110803bd8c1aedacc36788e6fd028944314 http://lists.opensuse.org/opensuse-security-announce/2009-04/msg00006.html http://secunia.com/advisories/34731 http://secunia.com/advisories/34750 http://secunia.com/advisories/34753 http://secunia.com/advisories/34771 http://secunia.com/advisories/34776 http://secunia.com/advisories/34785 http://secunia.com/advisories/34787 http://secunia.com/advisories/34801 http://slackware.com/sec • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
CVE-2009-1185 – Linux Kernel 2.6 (Debian 4.0 / Ubuntu / Gentoo) UDEV < 1.4.1 - Local Privilege Escalation
https://notcve.org/view.php?id=CVE-2009-1185
udev before 1.4.1 does not verify whether a NETLINK message originates from kernel space, which allows local users to gain privileges by sending a NETLINK message from user space. udev antes de v1.4.1 no verifica si un mensaje NETLINK es generado desde el espacio del kernel, lo que permite a usuarios locales obtener privilegios mediante el envio de un mensaje NETLIINK desde el espacio de usuario. Versions of udev < 1.4.1 do not verify that netlink messages are coming from the kernel.

CVE-2009-0115 – device-mapper-multipath: insecure permissions on multipathd.sock
https://notcve.org/view.php?id=CVE-2009-0115
The Device Mapper multipathing driver (aka multipath-tools or device-mapper-multipath) 0.4.8, as used in SUSE openSUSE, SUSE Linux Enterprise Server (SLES), Fedora, and possibly other operating systems, uses world-writable permissions for the socket file (aka /var/run/multipathd.sock), which allows local users to send arbitrary commands to the multipath daemon. multipath-tools en SUSE openSUSE v10.3 hasta v11.0 y SUSE Linux Enterprise Server (SLES) v10 utiliza permisos de escritura a todos para el fichero del socket (también conocido como /var/run/multipathd.sock), permitiendo a usuarios locales enviar comandos de su elección al demonio "multipath". • http://download.opensuse.org/update/10.3-test/repodata/patch-kpartx-6082.xml http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10691 http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10705 http://launchpad.net/bugs/cve/2009-0115 http://lists.opensuse.org/opensuse-security-announce/2009-03/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2009-04/msg00003.html http://lists.vmware.com/pipermail/security-announce/2010/000082.html http://secunia.com/advisories/ • CWE-732: Incorrect Permission Assignment for Critical Resource •
