CVE-2009-1630 – kernel: nfs: fix NFS v4 client handling of MAY_EXEC in nfs_permission
https://notcve.org/view.php?id=CVE-2009-1630
The nfs_permission function in fs/nfs/dir.c in the NFS client implementation in the Linux kernel 2.6.29.3 and earlier, when atomic_open is available, does not check execute (aka EXEC or MAY_EXEC) permission bits, which allows local users to bypass permissions and execute files, as demonstrated by files on an NFSv4 fileserver. La función nfs_permission en fs/nfs/dir.c en la implementación cliente NFS en Linux kernel v2.6.29.3 y versiones anteriores, cuando atomic_open está activo, no comprueba la ejecución (también conocido como EXEC or MAY_EXEC) de permisos de bits, lo cual permite a usuarios locales evitar permisos y ejecutar ficheros, como lo demostrado por ficheros en un servidor de ficheros NFSv4. • http://article.gmane.org/gmane.linux.nfs/26592 http://bugzilla.linux-nfs.org/show_bug.cgi?id=131 http://linux-nfs.org/pipermail/nfsv4/2006-November/005313.html http://linux-nfs.org/pipermail/nfsv4/2006-November/005323.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/35106 http://secunia.com/advisories/35298 http://secunia.com/advisories/35394 http • CWE-264: Permissions, Privileges, and Access Controls •

CVE-2009-1072 – kernel: nfsd should drop CAP_MKNOD for non-root
https://notcve.org/view.php?id=CVE-2009-1072
nfsd in the Linux kernel before 2.6.28.9 does not drop the CAP_MKNOD capability before handling a user request in a thread, which allows local users to create device nodes, as demonstrated on a filesystem that has been exported with the root_squash option. nfsd en el Kernel de Linux anteriores a la v2.6.28.9 no detiene la capacidad de CAP_MKNOD antes del manejo de una petición de usuario en un hilo, lo que permite a usuarios locales crear nodos de dispositivo, como se ha demostrado en un sistema de ficheros que ha sido exportado con la opción root_squash. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commitdiff%3Bh=76a67ec6fb79ff3570dcb5342142c16098299911 http://lists.opensuse.org/opensuse-security-announce/2009-04/msg00007.html 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://secunia.com/advisories/34422 http://secunia.com/advisories/34432 http://sec • CWE-16: Configuration •
CVE-2009-0778 – kernel: rt_cache leak leads to lack of network connectivity
https://notcve.org/view.php?id=CVE-2009-0778
The icmp_send function in net/ipv4/icmp.c in the Linux kernel before 2.6.25, when configured as a router with a REJECT route, does not properly manage the Protocol Independent Destination Cache (aka DST) in some situations involving transmission of an ICMP Host Unreachable message, which allows remote attackers to cause a denial of service (connectivity outage) by sending a large series of packets to many destination IP addresses within this REJECT route, related to an "rt_cache leak." La función icmp_send en net/ipv4/icmp.c en el kernel Linux anerior a v2.6.25, cuando se configura como un router con una ruta RECHAZADA, no gestiona apropiadamente el Protocolo Independiente de Caché de Destino (alias DST) en alguna situación que involucra transmisión de un mensaje ICMP Host inalcanzable, el cual permite a los atacantes remotos causar una denegación de servicio (conectividad parada) enviando una larga serie de paquetes a muchos direcciones IP de destino con esta ruta RECHAZADA, RELATIVA a "rt_cache leak." • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=7c0ecc4c4f8fd90988aab8a95297b9c0038b6160 http://openwall.com/lists/oss-security/2009/03/11/2 http://secunia.com/advisories/33758 http://secunia.com/advisories/37471 http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.25 http://www.redhat.com/support/errata/RHSA-2009-0326.html http://www.securityfocus.com/archive/1/507985/100/0/threaded http://www.securityfocus.com/bid/34084 http:/ • CWE-400: Uncontrolled Resource Consumption •
