CVE-2012-0879 – kernel: block: CLONE_IO io_context refcounting issues
https://notcve.org/view.php?id=CVE-2012-0879
The I/O implementation for block devices in the Linux kernel before 2.6.33 does not properly handle the CLONE_IO feature, which allows local users to cause a denial of service (I/O instability) by starting multiple processes that share an I/O context. La implementación I/O para dispositivos de bloque en el núcleo de Linux anteriores a v2.6.33 no maneja adecuadamente la característica CLONE_IO, lo cual permite a usuarios locales causar una denegación de servicio (inestabilidad I/O) arrancando múltiples procesos que comparten un contexto I/O. • http://ftp.osuosl.org/pub/linux/kernel/v2.6/ChangeLog-2.6.33 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=61cc74fbb87af6aa551a06a370590c9bc07e29d9 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=b69f2292063d2caf37ca9aec7d63ded203701bf3 http://lists.opensuse.org/opensuse-security-announce/2012-05/msg00013.html http://marc.info/?l=bugtraq&m=139447903326211&w=2 http://rhn.redhat.com/errata/RHSA-2012-0481.html http://rhn • CWE-400: Uncontrolled Resource Consumption •
CVE-2012-0247 – ImageMagick: invalid validation of images denial of service
https://notcve.org/view.php?id=CVE-2012-0247
ImageMagick 6.7.5-7 and earlier allows remote attackers to cause a denial of service (memory corruption) and possibly execute arbitrary code via crafted offset and count values in the ResolutionUnit tag in the EXIF IFD0 of an image. ImageMagick v6.7.5-7 y anteriores permite a atacantes remotos causar una denegación de servicio (corrupción de memoria) y posiblemente ejecutar código de su elección a través de desplazamientos (offsets) modificados y contar valores en la etiqueta ResolutionUnit en el EXIF IFD0 de una imagen . • http://rhn.redhat.com/errata/RHSA-2012-0544.html http://rhn.redhat.com/errata/RHSA-2012-0545.html http://secunia.com/advisories/47926 http://secunia.com/advisories/48247 http://secunia.com/advisories/48259 http://secunia.com/advisories/49043 http://secunia.com/advisories/49063 http://secunia.com/advisories/49068 http://ubuntu.com/usn/usn-1435-1 http://www.cert.fi/en/reports/2012/vulnerability595210.html http://www.debian.org/security/2012/dsa-2427 http://www& • CWE-20: Improper Input Validation •
