CVE-2011-4077 – kernel: xfs: potential buffer overflow in xfs_readlink()
https://notcve.org/view.php?id=CVE-2011-4077
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 •
CVE-2011-4330 – kernel: hfs: add sanity check for file name length
https://notcve.org/view.php?id=CVE-2011-4330
Stack-based buffer overflow in the hfs_mac2asc function in fs/hfs/trans.c in the Linux kernel 2.6 allows local users to cause a denial of service (crash) and possibly execute arbitrary code via an HFS image with a crafted len field. Un desbordamiento de búfer basado en pila en la función hfs_mac2asc en fs/hfs/trans.c en el kernel de Linux v2.6 permite a usuarios locales provocar una denegación de servicio (mediante caída del sistema) y posiblemente ejecutar código de su elección a través de una imagen HFS con un campo 'len' modificado. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commitdiff%3Bh=bc5b8a9003132ae44559edd63a1623 http://www.openwall.com/lists/oss-security/2011/11/21/14 http://www.openwall.com/lists/oss-security/2011/11/21/5 http://www.securityfocus.com/bid/50750 https://bugzilla.redhat.com/show_bug.cgi?id=755431 https://lkml.org/lkml/2011/11/9/303 https://access.redhat.com/security/cve/CVE-2011-4330 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVE-2011-4132 – kernel: jbd/jbd2: invalid value of first log block leads to oops
https://notcve.org/view.php?id=CVE-2011-4132
The cleanup_journal_tail function in the Journaling Block Device (JBD) functionality in the Linux kernel 2.6 allows local users to cause a denial of service (assertion error and kernel oops) via an ext3 or ext4 image with an "invalid log first block value." La función cleanup_journal_tail en la funcionalidad JBD (Journaling Block Device) del kernel de Linux v2.6 permite a usuarios locales provocar una denegación de servicio (error de aserción y fallo del kernel) a través de una imagen ext3 o ext4 con un "valor del primero bloque de registro no válido." • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commitdiff%3Bh=8762202dd0d6e46854f786bdb6fb3780a1625efe 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://securitytracker.com/id?1026325 http://www.openwall.com/lists/oss-security/2011/11/11/6 http://www.openwall.com/lists/oss-security/2011/11/13/4 http://www.securityfocus.com/ • CWE-20: Improper Input Validation •
CVE-2011-4081 – kernel: crypto: ghash: null pointer deref if no key is set
https://notcve.org/view.php?id=CVE-2011-4081
crypto/ghash-generic.c in the Linux kernel before 3.1 allows local users to cause a denial of service (NULL pointer dereference and OOPS) or possibly have unspecified other impact by triggering a failed or missing ghash_setkey function call, followed by a (1) ghash_update function call or (2) ghash_final function call, as demonstrated by a write operation on an AF_ALG socket. crypto/ghash-generic.c en el kernel de Linux antes de v3.1 permite a usuarios locales causar una denegación de servicio (desreferencia de puntero NULL y OOPS) o posiblemente tener un impacto no especificado mediante la activación de un fallo o ausencia de llamada a la función ghash_setkey, seguido por una (1) llamada a la función ghash_update o (2) llamada a la función ghash_final, como se demuestra por una operación de escritura en un socket AF_ALG. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=7ed47b7d142ec99ad6880bbbec51e9f12b3af74c http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.1 http://www.openwall.com/lists/oss-security/2011/10/27/2 https://bugzilla.redhat.com/show_bug.cgi?id=749475 https://github.com/torvalds/linux/commit/7ed47b7d142ec99ad6880bbbec51e9f12b3af74c https://access.redhat.com/security/cve/CVE-2011-4081 • CWE-476: NULL Pointer Dereference •
