CVE-2010-4258 – Linux Kernel 2.6.37 (RedHat / Ubuntu 10.04) - 'Full-Nelson.c' Local Privilege Escalation
https://notcve.org/view.php?id=CVE-2010-4258
The do_exit function in kernel/exit.c in the Linux kernel before 2.6.36.2 does not properly handle a KERNEL_DS get_fs value, which allows local users to bypass intended access_ok restrictions, overwrite arbitrary kernel memory locations, and gain privileges by leveraging a (1) BUG, (2) NULL pointer dereference, or (3) page fault, as demonstrated by vectors involving the clear_child_tid feature and the splice system call. La función do_exit en kernel/exit.c en el kernel de Linux anteriores a v2.6.36.2 no gestiona de forma adecuada el KERNEL_DS y el valor get_fs, lo que permite a usuarios locales saltarse las restricciones access_ok, sobrescribiendo posiciones de memoria del kernel, y obtener privilegios mediante el aprovechamiento de un (1) ERROR, (2) desreferencia a un puntero NULL, o (3) error de página, como lo demuestró por vectores que implican la característica clear_child_tid en las llamadas al sistema de unión. • https://www.exploit-db.com/exploits/15704 http://archives.neohapsis.com/archives/fulldisclosure/2010-12/0086.html http://blog.nelhage.com/2010/12/cve-2010-4258-from-dos-to-privesc http://code.google.com/p/chromium-os/issues/detail?id=10234 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=33dd94ae1ccbfb7bf0fb6c692bc3d1c4269e6177 http://googlechromereleases.blogspot.com/2011/01/chrome-os-beta-channel-update.html http://lists.fedoraproject.org/pipermail/package-annou • CWE-269: Improper Privilege Management •
CVE-2010-4180 – openssl: NETSCAPE_REUSE_CIPHER_CHANGE_BUG ciphersuite downgrade attack
https://notcve.org/view.php?id=CVE-2010-4180
OpenSSL before 0.9.8q, and 1.0.x before 1.0.0c, when SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG is enabled, does not properly prevent modification of the ciphersuite in the session cache, which allows remote attackers to force the downgrade to an unintended cipher via vectors involving sniffing network traffic to discover a session identifier. OpenSSL en versiones anteriores a 0.9.8q y 1.0.x en versiones anteriores a 1.0.0c, cuando SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG está habilitado, no previene adecuadamente la modificación del conjunto de cifrado en la caché de sesión, lo que permite a atacantes remotos forzar la degradación para un cifrado no destinado a través de vectores que involucran rastreo de tráfico de red para descubrir un identificador de sesión. • http://cvs.openssl.org/chngview?cn=20131 http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c02794777 http://lists.apple.com/archives/security-announce/2011//Jun/msg00000.html http://lists.fedoraproject.org/pipermail/package-announce/2010-December/052027.html http://lists.fedoraproject.org/pipermail/package-announce/2010-December/052315.html http://lists.opensuse.org/opensuse-security-announce/2011-01/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2011-05/msg00005.html& •
CVE-2010-2941 – cups: cupsd memory corruption vulnerability
https://notcve.org/view.php?id=CVE-2010-2941
ipp.c in cupsd in CUPS 1.4.4 and earlier does not properly allocate memory for attribute values with invalid string data types, which allows remote attackers to cause a denial of service (use-after-free and application crash) or possibly execute arbitrary code via a crafted IPP request. ipp.c en cupsd en CUPS v1.4.4 y anteriores no asigna correctamente memoria para valores de atributo con tipos de datos de cadena inválidos, permitiendo a atacantes remotos provocar una denegación de servicio (uso después de liberación y caída de la aplicación) o posiblemente ejecutar código arbitrario mediante una solicitud IPP manipulada. • http://blogs.sun.com/security/entry/multiple_vulnerabilities_in_mozilla_firefox http://lists.apple.com/archives/security-announce/2010//Nov/msg00000.html http://lists.fedoraproject.org/pipermail/package-announce/2010-November/050977.html http://lists.fedoraproject.org/pipermail/package-announce/2010-November/051277.html http://lists.fedoraproject.org/pipermail/package-announce/2010-November/051301.html http://lists.opensuse.org/opensuse-security-announce/2010-12/msg00000.html http://rhn.redhat.com/errata/RHSA • CWE-416: Use After Free •
CVE-2010-3702 – xpdf: uninitialized Gfx::parser pointer dereference
https://notcve.org/view.php?id=CVE-2010-3702
The Gfx::getPos function in the PDF parser in xpdf before 3.02pl5, poppler 0.8.7 and possibly other versions up to 0.15.1, CUPS, kdegraphics, and possibly other products allows context-dependent attackers to cause a denial of service (crash) via unknown vectors that trigger an uninitialized pointer dereference. La función Gfx::getPos en el analizador PDF en Xpdf versión anterior a 3.02 PL5, Poppler versión 0.8.7 y posiblemente otras versiones hasta la 0.15.1, CUPS, kdegraphics, y posiblemente otros productos permite que los atacantes dependiendo del contexto generen una denegación de servicio (bloqueo) por medio de vectores desconocidos que desencadenan una desreferencia de puntero no inicializada. • ftp://ftp.foolabs.com/pub/xpdf/xpdf-3.02pl5.patch http://cgit.freedesktop.org/poppler/poppler/commit/?id=e853106b58d6b4b0467dbd6436c9bb1cfbd372cf http://lists.fedoraproject.org/pipermail/package-announce/2010-November/050268.html http://lists.fedoraproject.org/pipermail/package-announce/2010-November/050285.html http://lists.fedoraproject.org/pipermail/package-announce/2010-November/050390.html http://lists.fedoraproject.org/pipermail/package-announce/2010-October/049392.html http://lists.fedoraproject.org/pipermail/package • CWE-476: NULL Pointer Dereference •

Multiple integer overflows in the snd_ctl_new function in sound/core/control.c in the Linux kernel before 2.6.36-rc5-next-20100929 allow local users to cause a denial of service (heap memory corruption) or possibly have unspecified other impact via a crafted (1) SNDRV_CTL_IOCTL_ELEM_ADD or (2) SNDRV_CTL_IOCTL_ELEM_REPLACE ioctl call.
