https://notcve.org/view.php?id=CVE-2009-2904
A certain Red Hat modification to the ChrootDirectory feature in OpenSSH 4.8, as used in sshd in OpenSSH 4.3 in Red Hat Enterprise Linux (RHEL) 5.4 and Fedora 11, allows local users to gain privileges via hard links to setuid programs that use configuration files within the chroot directory, related to requirements for directory ownership. Ciertas modificaciones Ret Hat en ChrootDirectory feature en OpenSSH v4.8, como el usado en sshd en OpenSSH v4.3 en Red Hat Enterprise Linux (RHEL) v5.4 y Fedora v11, permite a usuarios locales obtener privilegios a través de enlaces fuertes en programas setuid que usa una configuración de ficheros con el chroot directory, relacionado con requerimientos para el propietario. • http://lists.fedoraproject.org/pipermail/package-announce/2010-March/038214.html http://lists.vmware.com/pipermail/security-announce/2010/000082.html http://osvdb.org/58495 http://secunia.com/advisories/38794 http://secunia.com/advisories/38834 http://secunia.com/advisories/39182 http://www.securityfocus.com/bid/36552 http://www.vupen.com/english/advisories/2010/0528 https://bugzilla.redhat.com/show_bug.cgi?id=522141 https://oval.cisecurity.org/repository/search/definition/oval%3Aorg • CWE-16: Configuration •

https://notcve.org/view.php?id=CVE-2008-4609
The TCP implementation in (1) Linux, (2) platforms based on BSD Unix, (3) Microsoft Windows, (4) Cisco products, and probably other operating systems allows remote attackers to cause a denial of service (connection queue exhaustion) via multiple vectors that manipulate information in the TCP state table, as demonstrated by sockstress. La implementación del protocolo TCP en (1) Linux, (2) plataformas basadas en BSD Unix, (3) Microsoft Windows, (4) productos Cisco, y probablemente otros sistemas operativos, permite a atacantes remotos provocar una denegación de servicio (agotamiento de cola de conexión) a través de múltiples vectores que manipulan información en la tabla de estados del TCP, como lo demuestra sockstress. • http://blog.robertlee.name/2008/10/conjecture-speculation.html http://insecure.org/stf/tcp-dos-attack-explained.html http://lists.immunitysec.com/pipermail/dailydave/2008-October/005360.html http://marc.info/?l=bugtraq&m=125856010926699&w=2 http://searchsecurity.techtarget.com.au/articles/27154-TCP-is-fundamentally-borked http://www.cisco.com/en/US/products/products_security_advisory09186a0080af511d.shtml http://www.cisco.com/en/US/products/products_security_response09186a0080a15120.html http://www.cpni • CWE-16: Configuration •
CVE-2008-3831 – kernel: i915 kernel drm driver arbitrary ioremap
https://notcve.org/view.php?id=CVE-2008-3831
The i915 driver in (1) drivers/char/drm/i915_dma.c in the Linux kernel 2.6.24 on Debian GNU/Linux and (2) sys/dev/pci/drm/i915_drv.c in OpenBSD does not restrict the DRM_I915_HWS_ADDR ioctl to the Direct Rendering Manager (DRM) master, which allows local users to cause a denial of service (memory corruption) via a crafted ioctl call, related to absence of the DRM_MASTER and DRM_ROOT_ONLY flags in the ioctl's configuration. El driver i915 en (1) drivers/char/drm/i915_dma.c en el kernel v2.6.24 de Linux en Debian GNU/Linux y (2) sys/dev/pci/drm/i915_drv.c en OpenBSD no restringe el DRM_I915_HWS_ADDR ioctl al Direct Rendering Manager (DRM) master, lo cual permite a usuarios locales provocar una denegación de servicio (corrupción de memoria) mediante una llamada ioctl manipulada, relacionado con la ausencia de los indicadores DRM_MASTER y DRM_ROOT_ONLY en la configuración de los ioctl. • http://archives.neohapsis.com/archives/openbsd/cvs/2008-10/0365.html http://secunia.com/advisories/32315 http://secunia.com/advisories/32386 http://secunia.com/advisories/32709 http://secunia.com/advisories/32918 http://secunia.com/advisories/33182 http://secunia.com/advisories/33586 http://security.debian.org/pool/updates/main/l/linux-2.6.24/linux-2.6.24_2.6.24-6~etchnhalf.6.diff.gz http://securitytracker.com/id?1021065 http://sunsolve.sun.com/search/document.do • CWE-399: Resource Management Errors •
CVE-2008-4109
https://notcve.org/view.php?id=CVE-2008-4109
A certain Debian patch for OpenSSH before 4.3p2-9etch3 on etch; before 4.6p1-1 on sid and lenny; and on other distributions such as SUSE uses functions that are not async-signal-safe in the signal handler for login timeouts, which allows remote attackers to cause a denial of service (connection slot exhaustion) via multiple login attempts. NOTE: this issue exists because of an incorrect fix for CVE-2006-5051. Cierto parche de Debian para OpenSSH en versiones anteriores a 4.3p2-9etch3 en etch, y versiones anteriores a 4.6p1-1 en sid y lenny, que utiliza funciones que no son señales asíncronas seguras (async-signal-safe) en el gestor de señales para los tiempos de autentificado, el cual permite a los atacantes remotos causar una denegación de servicio (agotamiento de la ranura de conexión) a través de múltiples intentos de autenticación. NOTA: esto existe por una incorrecta solución de CVE-2006-5051. • http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=498678 http://lists.opensuse.org/opensuse-security-announce/2008-10/msg00004.html http://secunia.com/advisories/31885 http://secunia.com/advisories/32080 http://secunia.com/advisories/32181 http://www.debian.org/security/2008/dsa-1638 http://www.openwall.com/lists/oss-security/2024/07/01/3 http://www.securitytracker.com/id?1020891 http://www.ubuntu.com/usn/usn-649-1 https://exchange.xforce.ibmcloud.com/vulnerabilities/4520 • CWE-264: Permissions, Privileges, and Access Controls •
