CVE-2011-1581 – kernel: bonding: Incorrect TX queue offset
https://notcve.org/view.php?id=CVE-2011-1581
The bond_select_queue function in drivers/net/bonding/bond_main.c in the Linux kernel before 2.6.39, when a network device with a large number of receive queues is installed but the default tx_queues setting is used, does not properly restrict queue indexes, which allows remote attackers to cause a denial of service (BUG and system crash) or possibly have unspecified other impact by sending network traffic. La función bond_select_queue en drivers/net/bonding/bond_main.c en el kernel de Linux anteriores a v2.6.39, cuando esta configurado un dispositivo de red con un gran número de colas de recepción pero el tx_queues es el predeterminado, no restringen adecuadamente los índices de cola, lo que permite a atacantes remotos provocar una denegación de servicio (BUG y caída del sistema) o posiblemente tener un impacto no especificado mediante el envío de tráfico de red. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=fd0e435b0fe85622f167b84432552885a4856ac8 http://openwall.com/lists/oss-security/2011/04/13/16 http://openwall.com/lists/oss-security/2011/04/13/4 http://securitytracker.com/id?1025558 http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.39 https://bugzilla.redhat.com/show_bug.cgi?id=696029 https://access.redhat.com/security/cve/CVE-2011-1581 • CWE-20: Improper Input Validation •
CVE-2010-4805 – kernel: unlimited socket backlog DoS
https://notcve.org/view.php?id=CVE-2010-4805
The socket implementation in net/core/sock.c in the Linux kernel before 2.6.35 does not properly manage a backlog of received packets, which allows remote attackers to cause a denial of service by sending a large amount of network traffic, related to the sk_add_backlog function and the sk_rmem_alloc socket field. NOTE: this vulnerability exists because of an incomplete fix for CVE-2010-4251. La implementación del socket en net/core/sock.c en el kernel de Linux anteriores a v2.6.35 no maneja correctamente un retraso de los paquetes recibidos, lo que permite a atacantes remotos provocar una denegación de servicio mediante el envío de una gran cantidad de tráfico de la red, relacionados con la función sk_add_backlog y el campo de toma de sk_rmem_alloc. NOTA: esta vulnerabilidad existe debido a una solución incompleta para CVE-2010-4251. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=c377411f2494a931ff7facdbb3a6839b1266bcf6 http://kerneltrap.org/mailarchive/linux-netdev/2010/3/3/6271093/thread http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.35 http://www.securityfocus.com/bid/46637 https://bugzilla.redhat.com/show_bug.cgi?id=657303 https://access.redhat.com/security/cve/CVE-2010-4805 • CWE-400: Uncontrolled Resource Consumption •
CVE-2011-1476
https://notcve.org/view.php?id=CVE-2011-1476
Integer underflow in the Open Sound System (OSS) subsystem in the Linux kernel before 2.6.39 on unspecified non-x86 platforms allows local users to cause a denial of service (memory corruption) by leveraging write access to /dev/sequencer. Un desbordamiento de entero en el subsistema 'Open Sound System' (OSS) del kernel de Linux en versiones anteriores a v2.6.39 en plataformas no-x86 permite a usuarios locales provocar una denegación de servicio (corrupción de memoria) mediante el aprovechamiento del acceso de escritura a /dev/sequencer. • http://ftp.osuosl.org/pub/linux/kernel/v2.6/ChangeLog-2.6.39 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=b769f49463711205d57286e64cf535ed4daf59e9 http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00020.html http://www.openwall.com/lists/oss-security/2011/03/25/1 https://github.com/torvalds/linux/commit/b769f49463711205d57286e64cf535ed4daf59e9 • CWE-189: Numeric Errors •

https://notcve.org/view.php?id=CVE-2011-1493
Array index error in the rose_parse_national function in net/rose/rose_subr.c in the Linux kernel before 2.6.39 allows remote attackers to cause a denial of service (heap memory corruption) or possibly have unspecified other impact by composing FAC_NATIONAL_DIGIS data that specifies a large number of digipeaters, and then sending this data to a ROSE socket.
