CVE-2011-1598 – kernel: missing check in can/bcm and can/raw socket releases
https://notcve.org/view.php?id=CVE-2011-1598
The bcm_release function in net/can/bcm.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 bcm_release en net/can/bcm.c del kernel de linux en versiones anteriores a v2.6.39-rc6 no valida correctamente una estructura de toma de datos, lo cual permite a usuarios locales causar una denegación de servicio ( desreferenciar un puntero NULL ) o posiblemente tener un impacto no especificado a través de una operación de liberación manipulada. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=c6914a6f261aca0c9f715f883a353ae7ff51fe83 http://openwall.com/lists/oss-security/2011/04/20/2 http://openwall.com/lists/oss-security/2011/04/20/6 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/l • CWE-476: NULL Pointer Dereference •
CVE-2011-1746 – kernel: agp: insufficient page_count parameter checking in agp_allocate_memory()
https://notcve.org/view.php?id=CVE-2011-1746
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 •
CVE-2011-2022 – kernel: agp: insufficient pg_start parameter checking in AGPIOC_BIND and AGPIOC_UNBIND ioctls
https://notcve.org/view.php?id=CVE-2011-2022
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 • CWE-20: Improper Input Validation •
CVE-2011-1090 – kernel: nfs4: Ensure that ACL pages sent over NFS were not allocated from the slab
https://notcve.org/view.php?id=CVE-2011-1090
The __nfs4_proc_set_acl function in fs/nfs/nfs4proc.c in the Linux kernel before 2.6.38 stores NFSv4 ACL data in memory that is allocated by kmalloc but not properly freed, which allows local users to cause a denial of service (panic) via a crafted attempt to set an ACL. La función __nfs4_proc_set_ac en fs/nfs/nfs4proc.c en el Kernel de Linux anterior a v.2.6.38 almacena datos NFSv4 ACL en memoria que es asignado por kmalloc pero no libera adecuadamente, lo que permite a usuarios locales provocar una denegación de servicio (pánico) a través de intentos manipulados para establecer un ACL. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=e9e3d724e2145f5039b423c290ce2b2c3d8f94bc http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00020.html http://openwall.com/lists/oss-security/2011/03/07/12 http://openwall.com/lists/oss-security/2011/03/07/2 http://secunia.com/advisories/46397 http://securitytracker.com/id?1025336 http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.38 http://www.securityfocus.com/archive/1/52 • CWE-399: Resource Management Errors •
CVE-2011-1747
https://notcve.org/view.php?id=CVE-2011-1747
The agp subsystem in the Linux kernel 2.6.38.5 and earlier does not properly restrict memory allocation by the (1) AGPIOC_RESERVE and (2) AGPIOC_ALLOCATE ioctls, which allows local users to cause a denial of service (memory consumption) by making many calls to these ioctls. El subsistema agp en el kernel de Linux v2.6.38.5 y anteriores no restringe correctamente la asignación de memoria por el ( 1 ) AGPIOC_RESERVE y ( 2 )AGPIOC_ALLOCATE ioctls , lo cual permite a usuarios locales causar una denegación de servicio ( consumo de memoria ) haciendo muchas llamadas a estos ioctls. • 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/2011/04/22/10 http://openwall.com/lists/oss-security/2011/04/22/11 http://openwall.com/lists/oss-security/2011/04/22/7 http://openwall.com/lists/oss-security/2011/04/22/8 http://openwall.com/lists/oss-security/2011/04/22/9 http://securitytracker.c • CWE-399: Resource Management Errors •
