CVSS: 4.9EPSS: 0%CPEs: 6EXPL: 0CVE-2011-2689 – kernel: gfs2: make sure fallocate bytes is a multiple of blksize
https://notcve.org/view.php?id=CVE-2011-2689
The gfs2_fallocate function in fs/gfs2/file.c in the Linux kernel before 3.0-rc1 does not ensure that the size of a chunk allocation is a multiple of the block size, which allows local users to cause a denial of service (BUG and system crash) by arranging for all resource groups to have too little free space. La función gfs2_fallocate en fs/gfs2/file.c en el kernel de Linux anterior a v3.0-rc1 no garantiza que el tamaño de un trozo de asignación sea un múltiplo del tamaño de bloque, lo que permite a usuarios locales provocar una denegación de servicio (BUG y caída del sistema) mediante la organización de todos los grupos de recursos para tener un espacio libre muy reducido. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=6905d9e4dda6112f007e9090bca80507da158e63 http://marc.info/?l=bugtraq&m=139447903326211&w=2 http://rhn.redhat.com/errata/RHSA-2011-1065.html http://secunia.com/advisories/45193 http://securitytracker.com/id?1025776 http://www.kernel.org/pub/linux/kernel/v3.0/testing/ChangeLog-3.0-rc1 http://www.openwall.com/lists/oss-security/2011/07/13/1 http://www.securityfocus.com/bid/48677 https://bu • CWE-400: Uncontrolled Resource Consumption •

https://notcve.org/view.php?id=CVE-2011-2492
The bluetooth subsystem in the Linux kernel before 3.0-rc4 does not properly initialize certain data structures, which allows local users to obtain potentially sensitive information from kernel memory via a crafted getsockopt system call, related to (1) the l2cap_sock_getsockopt_old function in net/bluetooth/l2cap_sock.c and (2) the rfcomm_sock_getsockopt_old function in net/bluetooth/rfcomm/sock.c. El subsistema de bluetooth en el kernel de Linux anteriores a v3.0-rc4 no inicializa correctamente algunas estructuras de datos, lo que permite a usuarios locales obtener información sensible de la memoria del kernel a través de una llamada getsockopt manipulada, en relación con (1) la función l2cap_sock_getsockopt_old en net/bluetooth/l2cap_sock.c y (2) la función rfcomm_sock_getsockopt_old en net/bluetooth/rfcomm/sock.c. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=8d03e971cf403305217b8e62db3a2e5ad2d6263f http://marc.info/?l=bugtraq&m=139447903326211&w=2 http://permalink.gmane.org/gmane.linux.bluez.kernel/12909 http://rhn.redhat.com/errata/RHSA-2011-0927.html http://securitytracker.com/id?1025778 http://www.kernel.org/pub/linux/kernel/v3.0/testing/ChangeLog-3.0-rc4 http://www.openwall.com/lists/oss-security/2011/06/24/2 http://www.openwall.com/lists/ • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

The execve function in the Linux kernel, possibly 2.6.30-rc6 and earlier, does not properly clear the current->clear_child_tid pointer, which allows local users to cause a denial of service (memory corruption) or possibly gain privileges via a clone system call with CLONE_CHILD_SETTID or CLONE_CHILD_CLEARTID enabled, which is not properly handled during thread creation and exit. Una función execve en el kernel de Linux, posiblemente versión 2.6.30-rc6 y anteriores, no borra apropiadamente el puntero de current-)clear_child_tid, lo que permite a los usuarios locales causar una denegación de servicio (corrupción de memoria) o posiblemente alcanzar privilegios por medio de un sistema de clonación que llama con CLONE_CHILD_SETTID o CLONE_CHILD_CLEARTID habilitadas, que no son manejados apropiadamente durante la creación y salida de hilos (subprocesos). • http://article.gmane.org/gmane.linux.kernel/871942 http://lists.opensuse.org/opensuse-security-announce/2009-11/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2009-11/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2010-02/msg00005.html http://rhn.redhat.com/errata/RHSA-2009-1243.html http://secunia.com/advisories/35983 http://secunia.com/advisories/36501 http://secunia.com/advisories/36562 http://secunia.com/advisories/36759 http://secunia.com • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-269: Improper Privilege Management •

The asn1_decode_generaltime function in lib/krb5/asn.1/asn1_decode.c in the ASN.1 GeneralizedTime decoder in MIT Kerberos 5 (aka krb5) before 1.6.4 allows remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code via vectors involving an invalid DER encoding that triggers a free of an uninitialized pointer.
