https://notcve.org/view.php?id=CVE-2011-4325
The NFS implementation in Linux kernel before 2.6.31-rc6 calls certain functions without properly initializing certain data, which allows local users to cause a denial of service (NULL pointer dereference and O_DIRECT oops), as demonstrated using diotest4 from LTP. La implementación de NFS en el kernel de Linux antes de v2.6.31-rc6 llama a ciertas funciones sin inicializar adecuadamente ciertos datos, lo que permite a usuarios locales provocar una denegación de servicio (desrefenrencia de puntero NULL y oops de O_DIRECT), como se demuestra usando diotest4 de LTP. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commitdiff%3Bh=1ae88b2e4 http://www.securityfocus.com/bid/51366 https://bugzilla.redhat.com/show_bug.cgi?id=755455 https://exchange.xforce.ibmcloud.com/vulnerabilities/72297 https://access.redhat.com/security/cve/CVE-2011-4325 • CWE-476: NULL Pointer Dereference •

The Linux kernel before 3.2.2 does not properly restrict SG_IO ioctl calls, which allows local users to bypass intended restrictions on disk read and write operations by sending a SCSI command to (1) a partition block device or (2) an LVM volume. El kernel de Linux anterior a v3.2.2 no restringe adecuadamente llamadas SG_IO ioctl, permitiendo a usuarios locales eludir restricciones de lectura y escritura en disco mediante el envío de un comando SCSI a (1) un dispositivo de bloques de particiones o (2) un volumen LVM. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=0bfc96cb77224736dfa35c3c555d37b3646ef35e http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=ec8013beddd717d1740cfefb1a9b900deef85462 http://lists.opensuse.org/opensuse-security-announce/2012-04/msg00021.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00020.html http://secunia.com/advisories/48898 http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.2.2 http://www& • CWE-264: Permissions, Privileges, and Access Controls CWE-284: Improper Access Control •

Buffer overflow in the xfs_readlink function in fs/xfs/xfs_vnodeops.c in XFS in the Linux kernel 2.6, when CONFIG_XFS_DEBUG is disabled, allows local users to cause a denial of service (memory corruption and crash) and possibly execute arbitrary code via an XFS image containing a symbolic link with a long pathname. Un desbordamiento de búfer en la función xfs_readlink en fs/xfs/xfs_vnodeops.c en XFS en el kernel de Linux v2.6, cuando CONFIG_XFS_DEBUG está desactivado, permite a usuarios locales provocar una denegación de servicio (corrupción de memoria y caída del sistema) y posiblemente ejecutar código de su elección a través de una imagen XFS que contiene un enlace simbólico con una ruta demasiado larga. • http://marc.info/?l=bugtraq&m=139447903326211&w=2 http://oss.sgi.com/archives/xfs/2011-10/msg00345.html http://secunia.com/advisories/48964 http://www.openwall.com/lists/oss-security/2011/10/26/1 http://www.openwall.com/lists/oss-security/2011/10/26/3 http://xorl.wordpress.com/2011/12/07/cve-2011-4077-linux-kernel-xfs-readlink-memory-corruption https://bugzilla.redhat.com/show_bug.cgi?id=749156 https://access.redhat.com/security/cve/CVE-2011-4077 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
