https://notcve.org/view.php?id=CVE-2010-3078
The xfs_ioc_fsgetxattr function in fs/xfs/linux-2.6/xfs_ioctl.c in the Linux kernel before 2.6.36-rc4 does not initialize a certain structure member, which allows local users to obtain potentially sensitive information from kernel stack memory via an ioctl call. La función xfs_ioc_fsgetxattr en fs/xfs/linux-2.6/xfs_ioctl.c del kernel Linux anterior a v2.6.36-rc4 no inicializa apropiadamente ciertos miembros de estructura, lo que permite a usuarios locales obtener información potencialmente sensible de la pila de memoria del kernel a través de una llamada ioctl. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=a122eb2fdfd78b58c6dd992d6f4b1aaef667eef9 http://lists.opensuse.org/opensuse-security-announce/2010-09/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2010-10/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2010-11/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2011-02/msg00000.html http://secunia.com/advisories/41284 http://secunia.com/advisories/41512 http://secunia • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-401: Missing Release of Memory after Effective Lifetime •
CVSS: 7.8EPSS: 0%CPEs: 9EXPL: 2CVE-2010-3081 – Linux Kernel 2.6.27 < 2.6.36 (RedHat x86-64) - 'compat' Local Privilege Escalation
https://notcve.org/view.php?id=CVE-2010-3081
The compat_alloc_user_space functions in include/asm/compat.h files in the Linux kernel before 2.6.36-rc4-git2 on 64-bit platforms do not properly allocate the userspace memory required for the 32-bit compatibility layer, which allows local users to gain privileges by leveraging the ability of the compat_mc_getsockopt function (aka the MCAST_MSFILTER getsockopt support) to control a certain length value, related to a "stack pointer underflow" issue, as exploited in the wild in September 2010. Las funciones compat_alloc_user_space en los ficheros include/asm/compat.h del kernel de Linux en versiones anteriores a la v2.6.36-rc4-git2 en plataformas de 64-bit no reservan adecuadamente la memoria del espacio de usuario requerida para la capa de compatibilidad de 32-bit, lo que permite a usuarios locales escalar privilegios basándose en la capacidad de la función compat_mc_getsockopt (también conocido como soporte MCAST_MSFILTER getsockopt) para controlar un valor de longitud determinado, relacionado con un "stack pointer underflow", como se ha demostrado en septiembre del 2010. • https://www.exploit-db.com/exploits/15024 http://archives.neohapsis.com/archives/fulldisclosure/2010-09/0273.html http://archives.neohapsis.com/archives/fulldisclosure/2010-09/0278.html http://blog.ksplice.com/2010/09/cve-2010-3081 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=c41d68a513c71e35a14f66d71782d27a79a81ea6 http://isc.sans.edu/diary.html?storyid=9574 http://lists.opensuse.org/opensuse-security-announce/2010-09/msg00006.html http://lists.opensuse. • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

The keyctl_session_to_parent function in security/keys/keyctl.c in the Linux kernel 2.6.35.4 and earlier expects that a certain parent session keyring exists, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a KEYCTL_SESSION_TO_PARENT argument to the keyctl function. La función keyctl_session_to_parent en security/keys/keyctl.c en el kernel de Linux v2.6.35.4 y anteriores, espera que determinados keyrings de sesión aparezcan, lo que permite a usuarios locales provocar una denegación de servicio(deferencia a puntero nulo y caída de sistema) o posiblemente tener otro impacto sin especificar a través del argumento KEYCTL_SESSION_TO_PARENT a la función keyctl. • http://lists.opensuse.org/opensuse-security-announce/2010-10/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2011-02/msg00000.html http://secunia.com/advisories/41263 http://securitytracker.com/id?1024384 http://twitter.com/taviso/statuses/22777866582 http://www.openwall.com/lists/oss-security/2010/09/02/1 http://www.securityfocus.com/bid/42932 http://www.ubuntu.com/usn/USN-1000-1 http://www.vupen.com/english/advisories/2011/0298 https://bugzilla.redhat.c • CWE-476: NULL Pointer Dereference •

The pppol2tp_xmit function in drivers/net/pppol2tp.c in the L2TP implementation in the Linux kernel before 2.6.34 does not properly validate certain values associated with an interface, which allows attackers to cause a denial of service (NULL pointer dereference and OOPS) or possibly have unspecified other impact via vectors related to a routing change.

https://notcve.org/view.php?id=CVE-2010-2524
The DNS resolution functionality in the CIFS implementation in the Linux kernel before 2.6.35, when CONFIG_CIFS_DFS_UPCALL is enabled, relies on a user's keyring for the dns_resolver upcall in the cifs.upcall userspace helper, which allows local users to spoof the results of DNS queries and perform arbitrary CIFS mounts via vectors involving an add_key call, related to a "cache stuffing" issue and MS-DFS referrals. La funcionalidad de resolución DNS en el kernel de Linux anterior a v2.6.35, cuando CONFIG_CIFS_DFS_UPCALL está activado, cuenta con el "keyring" de usuario para la "upcall" dns_resolver en el espacio de usuario cifs.upcall, lo que permite a usuarios locales secuestrar los resultados de las consultas DNS y realizar montajes (mounts) CIFS de su elección a través de vectores que involucran una llamada add_key, relacionado con un cuestión de relleno de caché (stuffing) y referencias MS-DFS. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=4c0c03ca54f72fdd5912516ad0a23ec5cf01bda7 http://lists.opensuse.org/opensuse-security-announce/2010-09/msg00004.html http://marc.info/?l=oss-security&m=128072090331700&w=2 http://marc.info/?l=oss-security&m=128078387328921&w=2 http://marc.info/?l=oss-security&m=128080755321157&w=2 http://secunia.com/advisories/43315 http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.35 http://www.mandr •
