The encode_share_access function in fs/nfs/nfs4xdr.c in the Linux kernel before 2.6.29 allows local users to cause a denial of service (BUG and system crash) by using the mknod system call with a pathname on an NFSv4 filesystem. La función de encode_share_access fs/nfs/nfs4xdr.c en versiones del kernel de Linux anteriores a v2.6.29 permite a usuarios locales provocar una denegación de servicio (caída del sistema) mediante el uso de la llamada al sistema 'mknod' con una ruta de acceso en un sistema de archivos NFSv4. • http://ftp.osuosl.org/pub/linux/kernel/v2.6/ChangeLog-2.6.29 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=dc0b027dfadfcb8a5504f7d8052754bf8d501ab9 http://www.openwall.com/lists/oss-security/2012/02/06/3 https://bugzilla.redhat.com/show_bug.cgi?id=755440 https://github.com/torvalds/linux/commit/dc0b027dfadfcb8a5504f7d8052754bf8d501ab9 https://access.redhat.com/security/cve/CVE-2011-4324 •

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 •
