CVE-2009-2910 – kernel: x86_64 32 bit process register leak
https://notcve.org/view.php?id=CVE-2009-2910
arch/x86/ia32/ia32entry.S in the Linux kernel before 2.6.31.4 on the x86_64 platform does not clear certain kernel registers before a return to user mode, which allows local users to read register values from an earlier process by switching an ia32 process to 64-bit mode. arch/x86/ia32/ia32entry.S en el kernel de Linux anteriores a v2.6.31.4 en plataformas x86_64 no limpia adecuadamente ciertos registros del kernel antes de regresar al modo usuario, lo que permite a usuarios locales leer valores del registro desde un proceso anterior mediante el cambio de un proceso ia32 al modo 64-bit • http://git.kernel.org/?p=linux/kernel/git/x86/linux-2.6-tip.git%3Ba=commit%3Bh=24e35800cdc4350fc34e2bed37b608a9e13ab3b6 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://lkml.org/lkml/2009/10/1/164 http://marc.info/?l=oss-security&m=125442304214452&w=2 http://marc.info/?l=oss-security&m=125444390112831&w • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVE-2009-3612 – kernel: tcf_fill_node() infoleak due to typo in 9ef1d4c7
https://notcve.org/view.php?id=CVE-2009-3612
The tcf_fill_node function in net/sched/cls_api.c in the netlink subsystem in the Linux kernel 2.6.x before 2.6.32-rc5, and 2.4.37.6 and earlier, does not initialize a certain tcm__pad2 structure member, which might allow local users to obtain sensitive information from kernel memory via unspecified vectors. NOTE: this issue exists because of an incomplete fix for CVE-2005-4881. La función tcf_fill_node en net/sched/cls_api.c del subsistema netlink en el kernel de Linux v2.6.x hasta la v2.6.32-rc5, y v2.4.37.6 y anteriores, no inicializa un determinado miembro de la estructura tcm__pad2, lo que puede permitir a usuarios locales obtener información confidencial de la memoria del kernel a través de vectores de ataque sin especificar. NOTA: esta vulnerabilidad existe debido a una solución incompleta de CVE-2005-4881. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=ad61df918c44316940404891d5082c63e79c256a http://lists.opensuse.org/opensuse-security-announce/2009-12/msg00002.html http://lists.opensuse.org/opensuse-security-announce/2009-12/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2010-02/msg00005.html http://lists.vmware.com/pipermail/security-announce/2010/000082.html http://patchwork.ozlabs.org/patch/35412 http://secunia.com/advisories/37086 http://secunia& • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVE-2009-2698 – Linux Kernel < 2.6.19 (Debian 4) - 'udp_sendmsg' Local Privilege Escalation
https://notcve.org/view.php?id=CVE-2009-2698
The udp_sendmsg function in the UDP implementation in (1) net/ipv4/udp.c and (2) net/ipv6/udp.c in the Linux kernel before 2.6.19 allows local users to gain privileges or cause a denial of service (NULL pointer dereference and system crash) via vectors involving the MSG_MORE flag and a UDP socket. La función udp_sendmsg en la implementación UDP en los archivos (1) net/ipv4/udp.c y (2) net/ipv6/udp.c en el kernel de Linux anterior a versión 2.6.19, permite a los usuarios locales obtener privilegios o causar una denegación de servicio (Desreferencia de puntero NULL y bloqueo de sistema) por medio de vectores que involucran el flag MSG_MORE y un socket UDP. • https://www.exploit-db.com/exploits/9575 https://www.exploit-db.com/exploits/9574 https://www.exploit-db.com/exploits/9542 https://github.com/xiaoxiaoleo/CVE-2009-2698 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=1e0c14f49d6b393179f423abbac47f85618d3d46 http://lists.opensuse.org/opensuse-security-announce/2009-08/msg00008.html http://rhn.redhat.com/errata/RHSA-2009-1222.html http://rhn.redhat.com/errata/RHSA-2009-1223.html http://secunia.com • CWE-476: NULL Pointer Dereference •
CVE-2009-2848 – kernel: execve: must clear current->clear_child_tid
https://notcve.org/view.php?id=CVE-2009-2848
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 •
CVE-2009-1242
https://notcve.org/view.php?id=CVE-2009-1242
The vmx_set_msr function in arch/x86/kvm/vmx.c in the VMX implementation in the KVM subsystem in the Linux kernel before 2.6.29.1 on the i386 platform allows guest OS users to cause a denial of service (OOPS) by setting the EFER_LME (aka "Long mode enable") bit in the Extended Feature Enable Register (EFER) model-specific register, which is specific to the x86_64 platform. La función vmx_set_msr en arch/x86/kvm/vmx.c en la implementación VMX en el subsistema KVM en el kernel de Linux anteriores a v2.6.29.1 en la plataforma i386 permite a los usuarios invitados del SO causar una denegación de servicio (OOPS) estableciendo el bit EFER_LME (también conocido como "modo largo habilitado") en la Extended Feature Enable Register (EFER) registro específico de modelo, lo que es específico para la plataforma x86_64. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=16175a796d061833aacfbd9672235f2d2725df65 http://lists.opensuse.org/opensuse-security-announce/2009-06/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2009-06/msg00002.html http://openwall.com/lists/oss-security/2009/04/01/3 http://patchwork.kernel.org/patch/15549 http://secunia.com/advisories/34478 http://secunia.com/advisories/34981 http://secunia.com/advisories/35120 http://secunia.com • CWE-20: Improper Input Validation •
