CVE-2014-3956
https://notcve.org/view.php?id=CVE-2014-3956
The sm_close_on_exec function in conf.c in sendmail before 8.14.9 has arguments in the wrong order, and consequently skips setting expected FD_CLOEXEC flags, which allows local users to access unintended high-numbered file descriptors via a custom mail-delivery program. La función sm_close_on_exec en conf.c en sendmail anterior a 8.14.9 tiene argumentos en el orden erróneo, y como consecuencia evade configurar etiquetas FD_CLOEXEC esperadas, lo que permite a usuarios locales acceder a descriptores de archivos de número alto no intencionados a través de un programa de entrega de correo personalizado. • ftp://ftp.sendmail.org/pub/sendmail/RELEASE_NOTES http://advisories.mageia.org/MGASA-2014-0270.html http://lists.fedoraproject.org/pipermail/package-announce/2014-June/134349.html http://lists.opensuse.org/opensuse-updates/2014-06/msg00032.html http://lists.opensuse.org/opensuse-updates/2014-06/msg00033.html http://packetstormsecurity.com/files/126975/Slackware-Security-Advisory-sendmail-Updates.html http://secunia.com/advisories/57455 http://secunia.com/advisories/58628 http://security.gentoo.org • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVE-2013-6833
https://notcve.org/view.php?id=CVE-2013-6833
The qls_eioctl function in sys/dev/qlxge/qls_ioctl.c in the kernel in FreeBSD 10 and earlier does not validate a certain size parameter, which allows local users to obtain sensitive information from kernel memory via a crafted ioctl call. La función qls_eioctl en el archivo sys/dev/qlxge/qls_ioctl.c en el kernel en FreeBSD versión 10 y anteriores, no comprueba un parámetro de cierto tamaño, lo que permite a usuarios locales obtener información confidencial de la memoria del kernel por medio de una llamada ioctl diseñada. • http://archives.neohapsis.com/archives/fulldisclosure/2013-11/0107.html • CWE-20: Improper Input Validation •
CVE-2013-6832
https://notcve.org/view.php?id=CVE-2013-6832
The nand_ioctl function in sys/dev/nand/nand_geom.c in the nand driver in the kernel in FreeBSD 10 and earlier does not properly initialize a certain data structure, which allows local users to obtain sensitive information from kernel memory via a crafted ioctl call. La función nand_ioctl en el archivo sys/dev/nand/nand_geom.c en el controlador nand en el kernel en FreeBSD versión 10 y anteriores no inicializa apropiadamente una cierta estructura de datos, lo que permite a usuarios locales obtener información confidencial de la memoria del kernel por medio de una llamada ioctl diseñada. • http://archives.neohapsis.com/archives/fulldisclosure/2013-11/0106.html • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

La función ql_eioctl en el archivo sys/dev/qlxgbe/ql_ioctl.c en el kernel en FreeBSD versión 10 y anteriores, no comprueba un parámetro de tamaño determinado, lo que permite a usuarios locales obtener información confidencial de la memoria del kernel por medio de una llamada ioctl diseñada. • http://archives.neohapsis.com/archives/fulldisclosure/2013-11/0107.html • CWE-20: Improper Input Validation •
CVE-2012-0217 – FreeBSD - Intel SYSRET Privilege Escalation
https://notcve.org/view.php?id=CVE-2012-0217
The x86-64 kernel system-call functionality in Xen 4.1.2 and earlier, as used in Citrix XenServer 6.0.2 and earlier and other products; Oracle Solaris 11 and earlier; illumos before r13724; Joyent SmartOS before 20120614T184600Z; FreeBSD before 9.0-RELEASE-p3; NetBSD 6.0 Beta and earlier; Microsoft Windows Server 2008 R2 and R2 SP1 and Windows 7 Gold and SP1; and possibly other operating systems, when running on an Intel processor, incorrectly uses the sysret path in cases where a certain address is not a canonical address, which allows local users to gain privileges via a crafted application. NOTE: because this issue is due to incorrect use of the Intel specification, it should have been split into separate identifiers; however, there was some value in preserving the original mapping of the multi-codebase coordinated-disclosure effort to a single identifier. El modo de usuario Scheduler en el núcleo en Microsoft Windows Server v2008 R2 y R2 SP1 y Windows v7 Gold y SP1 sobre la plataforma x64 no maneja adecuadamente solicitudes del sistema, lo que permite a usuarios locales obtener privilegios a través de una aplicación modificada, también conocida como "vulnerabilidad de corrupción de memoria de modo de usuario Scheduler". It was found that the Xen hypervisor implementation as shipped with Red Hat Enterprise Linux 5 did not properly restrict the syscall return addresses in the sysret return path to canonical addresses. An unprivileged user in a 64-bit para-virtualized guest, that is running on a 64-bit host that has an Intel CPU, could use this flaw to crash the host or, potentially, escalate their privileges, allowing them to execute arbitrary code at the hypervisor level. • https://www.exploit-db.com/exploits/46508 https://www.exploit-db.com/exploits/28718 https://www.exploit-db.com/exploits/20861 http://blog.illumos.org/2012/06/14/illumos-vulnerability-patched http://blog.xen.org/index.php/2012/06/13/the-intel-sysret-privilege-escalation http://ftp.netbsd.org/pub/NetBSD/security/advisories/NetBSD-SA2012-003.txt.asc http://lists.xen.org/archives/html/xen-announce/2012-06/msg00001.html http://lists.xen.org/archives/html/xen-devel/2012-06 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
