CVSS: 6.1EPSS: 0%CPEs: 6EXPL: 0CVE-2011-1776 – kernel: validate size of EFI GUID partition entries
https://notcve.org/view.php?id=CVE-2011-1776
The is_gpt_valid function in fs/partitions/efi.c in the Linux kernel before 2.6.39 does not check the size of an Extensible Firmware Interface (EFI) GUID Partition Table (GPT) entry, which allows physically proximate attackers to cause a denial of service (heap-based buffer overflow and OOPS) or obtain sensitive information from kernel heap memory by connecting a crafted GPT storage device, a different vulnerability than CVE-2011-1577. La función is_gpt_valid en fs/partitions/efi.c en el kernel de Linux v2.6.39 no comprueba el tamaño de una Tabla de particiones GUID (GPT) de un Interface Firmware Extensible (EFI), lo que permite causar a atacantes físicamente próximos una denegación de servicio (desbordamiento de memoria basado en monticulo y OOPS) u obtener información confidencial de la memoria dinámica del kernel conectando un dispositivo GPT de almacenamiento hecho a mano. Se trata de una vulnerabilidad diferente a CVE-2011-1577. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=fa039d5f6b126fbd65eefa05db2f67e44df8f121 http://openwall.com/lists/oss-security/2011/05/10/4 http://rhn.redhat.com/errata/RHSA-2011-0927.html http://securityreason.com/securityalert/8369 http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.39 http://www.pre-cert.de/advisories/PRE-SA-2011-04.txt http://www.securityfocus.com/bid/47796 https://bugzilla.redhat.com/show_bug.cgi?id=703026 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

The raw_release function in net/can/raw.c in the Linux kernel before 2.6.39-rc6 does not properly validate a socket data structure, which allows local users to cause a denial of service (NULL pointer dereference) or possibly have unspecified other impact via a crafted release operation. La función raw_release en net/can/raw.c en el Kernel de Linux anterior a v2.6.39-rc6 no valida adecuadamente una estructura de datos socket, lo que permite a usuarios locales provocar una denegación de servicio (desreferencia a puntero NULL) o posiblemente tener otro impacto no especificado a través de una liberación de operación. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=10022a6c66e199d8f61d9044543f38785713cbbd http://openwall.com/lists/oss-security/2011/04/20/7 http://openwall.com/lists/oss-security/2011/04/21/1 http://openwall.com/lists/oss-security/2011/04/21/2 http://openwall.com/lists/oss-security/2011/04/21/7 http://openwall.com/lists/oss-security/2011/04/22/2 http://openwall.com/lists/oss-security/2011/04/25/4 http://permalink.gmane. • CWE-476: NULL Pointer Dereference •

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&#x • CWE-189: Numeric Errors •

The agp_generic_remove_memory function in drivers/char/agp/generic.c in the Linux kernel before 2.6.38.5 does not validate a certain start parameter, which allows local users to gain privileges or cause a denial of service (system crash) via a crafted AGPIOC_UNBIND agp_ioctl ioctl call, a different vulnerability than CVE-2011-1745. La función agp_generic_remove_memory en los drivers /char/agp/generic.c del kernel de Linux con anterioridad a v2.6.38.5 no valida un parámetro de inicio determinado, lo que permite a usuarios locales conseguir privilegios o causar una denegación de servicio ( fallo del sistema ) a través de una llamada manipulada AGPIOC_UNBIND agp_ioctl ioctl, es una vulnerabilidad diferente de CVE -2011- 1745. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=194b3da873fd334ef183806db751473512af29ce 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/47843 https://bugzilla.redhat.com/show_bug.cgi?id=698996 https://lkml.org/lkml/2011/4/14&#x • CWE-20: Improper Input Validation •
