CVSS: 6.9EPSS: 0%CPEs: 270EXPL: 0CVE-2011-1011 – policycoreutils: insecure temporary directory handling in seunshare
https://notcve.org/view.php?id=CVE-2011-1011
The seunshare_mount function in sandbox/seunshare.c in seunshare in certain Red Hat packages of policycoreutils 2.0.83 and earlier in Red Hat Enterprise Linux (RHEL) 6 and earlier, and Fedora 14 and earlier, mounts a new directory on top of /tmp without assigning root ownership and the sticky bit to this new directory, which allows local users to replace or delete arbitrary /tmp files, and consequently cause a denial of service or possibly gain privileges, by running a setuid application that relies on /tmp, as demonstrated by the ksu application. La función seunshare_mount en sandbox/seunshare.c en seunshare en ciertos paquetes de Red Hat de policycoreutils v2.0.83 y anteriores de Red Hat Enterprise Linux (RHEL) v6 y anteriores, y Fedora v14 y anteriores, monta un nuevo directorio en la parte superior de /tmp sin asignar la pertenencia de root y el bit sticky a este nuevo directorio, lo que permite a usuarios locales reemplazar o eliminar de archivos /tmp de su elección, y por lo tanto provocar una denegación de servicio o ganar privilegios en su caso, mediante la ejecución de una aplicación setuid que se basa en /tmp, como demostrado por la aplicación de KSU. • http://archives.neohapsis.com/archives/fulldisclosure/2011-02/0585.html http://lists.fedoraproject.org/pipermail/package-announce/2011-March/056227.html http://openwall.com/lists/oss-security/2011/02/23/1 http://openwall.com/lists/oss-security/2011/02/23/2 http://pkgs.fedoraproject.org/gitweb/?p=policycoreutils.git%3Ba=blob%3Bf=policycoreutils-rhat.patch%3Bh=d4db5bc06027de23d12a4b3f18fa6f9b1517df27%3Bhb=HEAD#l2197 http://secunia.com/advisories/43415 http://secunia.com/advisories/43844 http://secunia&# • CWE-264: Permissions, Privileges, and Access Controls •
CVSS: 7.8EPSS: 0%CPEs: 16EXPL: 0CVE-2009-3620 – kernel: r128 IOCTL NULL pointer dereferences when CCE state is uninitialised
https://notcve.org/view.php?id=CVE-2009-3620
The ATI Rage 128 (aka r128) driver in the Linux kernel before 2.6.31-git11 does not properly verify Concurrent Command Engine (CCE) state initialization, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly gain privileges via unspecified ioctl calls. El controlador ATI Rage 128 (también conocido como r128), en el Kernel de Linux anterior a v2.6.31-git11 no verifica de forma adecuada el estado de inicialización del "Concurrent Command Engine (CCE)", lo que permite a usuarios locales provocar una denegación de servicio (desreferenciación de puntero nulo y caída del sistema) o posiblemente obtener privilegios a través de llamadas ioctl sin especificar. • http://article.gmane.org/gmane.linux.kernel/892259 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=7dc482dfeeeefcfd000d4271c4626937406756d7 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.opensuse.org/opensuse-security-announce/2010-02/msg00007.html http://lists.vmware.com/pipermail/sec • CWE-476: NULL Pointer Dereference CWE-908: Use of Uninitialized Resource •

https://notcve.org/view.php?id=CVE-2008-4989
The _gnutls_x509_verify_certificate function in lib/x509/verify.c in libgnutls in GnuTLS before 2.6.1 trusts certificate chains in which the last certificate is an arbitrary trusted, self-signed certificate, which allows man-in-the-middle attackers to insert a spoofed certificate for any Distinguished Name (DN). La función _gnutls_x509_verify_certificate en lib/x509/verify.c en libgnutls en GnuTLS antes de v2.6.1 confía en las cadenas de certificado en las que el último certificado es un certificado de confianza arbitraria, auto-firmado, lo que permite a atacantes de tipo "hombre en el medio" (man-in-the-middle) insertar un certificado falso para cualquier Distinguished Name(DN). • http://article.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3215 http://article.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3217 http://lists.opensuse.org/opensuse-security-announce/2008-12/msg00002.html http://lists.opensuse.org/opensuse-security-announce/2009-04/msg00010.html http://secunia.com/advisories/32619 http://secunia.com/advisories/32681 http://secunia.com/advisories/32687 http://secunia.com/advisories/32879 http://secunia.com/advisories/33501 http://secunia.com/advi • CWE-295: Improper Certificate Validation •

https://notcve.org/view.php?id=CVE-2008-5021
nsFrameManager in Firefox 3.x before 3.0.4, Firefox 2.x before 2.0.0.18, Thunderbird 2.x before 2.0.0.18, and SeaMonkey 1.x before 1.1.13 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code by modifying properties of a file input element while it is still being initialized, then using the blur method to access uninitialized memory. nsFrameManager en Firefox v3.x antes de la v3.0.4, Firefox v2.x antes de la v2.0.0.18, Thunderbird 2.x antes de la v2.0.0.18, y SeaMonkey v1.x antes de la v1.1.13 permite a atacantes remotos producir una denegación de servicio (caída) y una posible ejecución de código a su elección modificación de las propiedades de un elemento de entrada de fichero mientras se inicia, cuando se esta utilizando el método blur para acceder a no ha sido inicializada. This vulnerability allows attackers to potentially execute arbitrary code on vulnerable installations of Mozilla Firefox. User interaction is required to exploit this vulnerability in that the target must visit a malicious page. The specific flaw exists when a DOM method on a specific HTML form object is called before the object itself has actually completed it's initialization. This will lead to a call of uninitialized data which can result in code execution under the context of the current user. • http://lists.opensuse.org/opensuse-security-announce/2008-11/msg00004.html http://secunia.com/advisories/32684 http://secunia.com/advisories/32693 http://secunia.com/advisories/32694 http://secunia.com/advisories/32695 http://secunia.com/advisories/32713 http://secunia.com/advisories/32714 http://secunia.com/advisories/32715 http://secunia.com/advisories/32721 http://secunia.com/advisories/32778 http://secunia.com/advisories/32798 http://secunia.com/advisories/32845 http:// • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
