CVE-2011-3585 – Samba mtab lock file race condition
https://notcve.org/view.php?id=CVE-2011-3585
Multiple race conditions in the (1) mount.cifs and (2) umount.cifs programs in Samba 3.6 allow local users to cause a denial of service (mounting outage) via a SIGKILL signal during a time window when the /etc/mtab~ file exists. Múltiples condiciones de carrera en los programas (1) mount.cifs y (2) umount.cifs en Samba versión 3.6, permiten a usuarios locales causar una denegación de servicio (interrupción del montaje) por medio de una señal SIGKILL durante una ventana de tiempo cuando existe el archivo /etc/mtab~. • https://bugzilla.redhat.com/show_bug.cgi?id=742907 https://bugzilla.samba.org/show_bug.cgi?id=7179 https://git.samba.org/?p=cifs-utils.git%3Ba=commitdiff%3Bh=810f7e4e0f2dbcbee0294d9b371071cb08268200 https://www.openwall.com/lists/oss-security/2011/09/27/1 https://www.openwall.com/lists/oss-security/2011/09/30/5 https://access.redhat.com/security/cve/CVE-2011-3585 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
CVE-2011-2517 – kernel: nl80211: missing check for valid SSID size in scan operations
https://notcve.org/view.php?id=CVE-2011-2517
Multiple buffer overflows in net/wireless/nl80211.c in the Linux kernel before 2.6.39.2 allow local users to gain privileges by leveraging the CAP_NET_ADMIN capability during scan operations with a long SSID value. Múltiples desbordamientos de búfer en net/wireless/nl80211.c en el kernel de Linux antes de v2.6.39.2 permite a usuarios locales obtener privilegios mediante el aprovechamiento de la capacidad CAP_NET_ADMIN durante las operaciones de exploración con un valor de SSID de largo. • http://ftp.osuosl.org/pub/linux/kernel/v2.6/ChangeLog-2.6.39.2 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=208c72f4fe44fe09577e7975ba0e7fa0278f3d03 http://rhn.redhat.com/errata/RHSA-2011-1212.html http://www.openwall.com/lists/oss-security/2011/07/01/4 https://bugzilla.redhat.com/show_bug.cgi?id=718152 https://github.com/torvalds/linux/commit/208c72f4fe44fe09577e7975ba0e7fa0278f3d03 https://access.redhat.com/security/cve/CVE-2011-2517 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVE-2011-1576 – kernel: net: Fix memory leak/corruption on VLAN GRO_DROP
https://notcve.org/view.php?id=CVE-2011-1576
The Generic Receive Offload (GRO) implementation in the Linux kernel 2.6.18 on Red Hat Enterprise Linux 5 and 2.6.32 on Red Hat Enterprise Linux 6, as used in Red Hat Enterprise Virtualization (RHEV) Hypervisor and other products, allows remote attackers to cause a denial of service via crafted VLAN packets that are processed by the napi_reuse_skb function, leading to (1) a memory leak or (2) memory corruption, a different vulnerability than CVE-2011-1478. Vulnerabilidad en la implementación de Generic Receive Offload (GRO) en el kernel de Linux versión 2.6.18 en Red Hat Enterprise Linux versiones 5 y 2.6.32 en Red Hat Enterprise Linux versión 6, tal y como se utiliza en el Hypervisor Red Hat Enterprise Virtualization (RHEV) y otros productos, permite a los atacantes remotos generar un denegación de servicio mediante paquetes VLAN creados que son procesados por la función napi_reuse_skb, lo que conduce a (1) una fuga de memoria o (2) daños en la memoria, una vulnerabilidad diferente a CVE-2011-1478. • http://rhn.redhat.com/errata/RHSA-2011-0927.html http://www.redhat.com/support/errata/RHSA-2011-1090.html http://www.redhat.com/support/errata/RHSA-2011-1106.html http://www.securityfocus.com/bid/48907 http://www.securitytracker.com/id?1025853 https://bugzilla.redhat.com/show_bug.cgi?id=695173 https://access.redhat.com/security/cve/CVE-2011-1576 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-401: Missing Release of Memory after Effective Lifetime •
CVE-2011-1182 – kernel signal spoofing issue
https://notcve.org/view.php?id=CVE-2011-1182
kernel/signal.c in the Linux kernel before 2.6.39 allows local users to spoof the uid and pid of a signal sender via a sigqueueinfo system call. kernel/signal.c en Linux kernel anterior a v2.6.39 permite a usuarios locales falsear el "uid" y el "pid" a través de un envío de señal de una llamada del sistema "sigqueueinfo". • 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=da48524eb20662618854bb3df2db01fc65f3070c http://rhn.redhat.com/errata/RHSA-2011-0927.html http://www.openwall.com/lists/oss-security/2011/03/23/2 https://bugzilla.redhat.com/show_bug.cgi?id=690028 https://github.com/torvalds/linux/commit/da48524eb20662618854bb3df2db01fc65f3070c https://access.redhat.com/security/cve/CVE-2011-1182 •
CVE-2011-1746 – kernel: agp: insufficient page_count parameter checking in agp_allocate_memory()

Multiple integer overflows in the (1) agp_allocate_memory and (2) agp_create_user_memory functions in drivers/char/agp/generic.c in the Linux kernel before 2.6.38.5 allow local users to trigger buffer overflows, and consequently cause a denial of service (system crash) or possibly have unspecified other impact, via vectors related to calls that specify a large number of memory pages. Multiples desbordamientos de enteros en las funciones agp_allocate_memory y agp_create_user_memory en los drivers /char/agp/generic.c del kernel de Linux con anterioridad a v2.6.38.5 permite a los usuarios locales provocar desbordamientos de búfer, y causar en consecuencia, una denegación de servicio ( caída del sistema ) o, posiblemente, tener un impacto no especificado, a través de vectores relacionados con las llamadas que especifican un amplio número de páginas de memoria. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=b522f02184b413955f3bc952e3776ce41edc6355 http://openwall.com/lists/oss-security/2011/04/21/4 http://openwall.com/lists/oss-security/2011/04/22/7 http://rhn.redhat.com/errata/RHSA-2011-0927.html http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.38.5 http://www.securityfocus.com/bid/47535 https://bugzilla.redhat.com/show_bug.cgi?id=698998 https://lkml.org/lkml/2011/4/14 • CWE-189: Numeric Errors •
