CVE-2009-0269 – kernel: ecryptfs readlink flaw
https://notcve.org/view.php?id=CVE-2009-0269
fs/ecryptfs/inode.c in the eCryptfs subsystem in the Linux kernel before 2.6.28.1 allows local users to cause a denial of service (fault or memory corruption), or possibly have unspecified other impact, via a readlink call that results in an error, leading to use of a -1 return value as an array index. El codigo fuente del fichero fs/ecryptfs/inode.c en el subsistema eCryptfs de versiones del kernel de Linux anteriores a la 2.6.28.1 permite a usuarios locales provocar una denegación de servicio (con fallo o corrupción de memoria), o posiblemente tener algún otro impacto no especificado, a través de una llamada a readlink que resulta en un error que provoca un valor de retorno -1 en el indice de un array. • http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.27.y.git%3Ba=commit%3Bh=a17d5232de7b53d34229de79ec22f4bb04adb7e4 http://lists.opensuse.org/opensuse-security-announce/2009-02/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2009-06/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2009-06/msg00001.html http://secunia.com/advisories/33758 http://secunia.com/advisories/34394 http://secunia.com/advisories/34502 http://secunia.com/advisories/34981 http: • CWE-787: Out-of-bounds Write •
CVE-2008-4989 – gnutls: certificate chain verification flaw
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 •
CVE-2008-4577 – dovecot: incorrect handling of negative rights in the ACL plugin
https://notcve.org/view.php?id=CVE-2008-4577
The ACL plugin in Dovecot before 1.1.4 treats negative access rights as if they are positive access rights, which allows attackers to bypass intended access restrictions. El plugin ACL en Dovecot anterior a 1.1.4 amenaza los derechos del acceso negativo como si fueran derechos de acceso positivos, lo que permite a atacantes evitar las restricciones de acceso previstas. • http://bugs.gentoo.org/show_bug.cgi?id=240409 http://lists.opensuse.org/opensuse-security-announce/2009-02/msg00002.html http://secunia.com/advisories/32164 http://secunia.com/advisories/32471 http://secunia.com/advisories/33149 http://secunia.com/advisories/33624 http://secunia.com/advisories/36904 http://security.gentoo.org/glsa/glsa-200812-16.xml http://www.dovecot.org/list/dovecot-news/2008-October/000085.html http://www.mandriva.com/security/advisories?name=MDVSA-2008:232& • CWE-863: Incorrect Authorization •
CVE-2008-1945 – qemu/kvm/xen: add image format options for USB storage and removable media
https://notcve.org/view.php?id=CVE-2008-1945
QEMU 0.9.0 does not properly handle changes to removable media, which allows guest OS users to read arbitrary files on the host OS by using the diskformat: parameter in the -usbdevice option to modify the disk-image header to identify a different format, a related issue to CVE-2008-2004. QEMU 0.9.0 no maneja apropiadamente cambio de medios extraíbles, lo cual permite a usuarios invitados del sistema operativo leer ficheros de su elección en el Host del sistema operativo utilizando el diskformat: parámetro en la opción -usbdevice para modificar la cabecera disk-image para identificar un formato diferente, una cuestión relacionada a CVE-2008-2004. • http://lists.opensuse.org/opensuse-security-announce/2009-04/msg00003.html http://secunia.com/advisories/32063 http://secunia.com/advisories/32088 http://secunia.com/advisories/34642 http://secunia.com/advisories/35031 http://secunia.com/advisories/35062 http://www.debian.org/security/2009/dsa-1799 http://www.mandriva.com/security/advisories?name=MDVSA-2008:162 http://www.securityfocus.com/bid/30604 http://www.securitytracker.com/id?1020959 http://www.ubuntu.com/usn/usn-776& •
CVE-2007-5729
https://notcve.org/view.php?id=CVE-2007-5729
The NE2000 emulator in QEMU 0.8.2 allows local users to execute arbitrary code by writing Ethernet frames with a size larger than the MTU to the EN0_TCNT register, which triggers a heap-based buffer overflow in the slirp library, aka NE2000 "mtu" heap overflow. NOTE: some sources have used CVE-2007-1321 to refer to this issue as part of "NE2000 network driver and the socket code," but this is the correct identifier for the mtu overflow vulnerability. El emulador NE2000 en QEMU 0.8.2 permite a usuarios locales ejecutar código de su elección a través de la escritura de la estructura ethernet con un tamaño mayor que el MTU en el registro EN0_TCNT, lo cual dispara un desbordamiento de búfer basado en pila en la libreria slirp, también conocida como desbordamiento de pila NE2000 "mtu". NOTA: algunas fuentes han utilizado CVE-2007-1321 para referenciar este asunto como una parte de "el controlado de red NE2000 y el código de conexión," pero este es el indentificador correcto para la vulnerabilidad de desbordamiento de mtu. • http://lists.opensuse.org/opensuse-security-announce/2009-01/msg00004.html http://osvdb.org/42986 http://secunia.com/advisories/25073 http://secunia.com/advisories/25095 http://secunia.com/advisories/27486 http://secunia.com/advisories/29129 http://secunia.com/advisories/33568 http://taviso.decsystem.org/virtsec.pdf http://www.attrition.org/pipermail/vim/2007-October/001842.html http://www.debian.org/security/2007/dsa-1284 http://www.mandriva.com/security/advisories?name=MDKSA& • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
