CVE-2012-0248 – ImageMagick: invalid validation of images denial of service
https://notcve.org/view.php?id=CVE-2012-0248
ImageMagick 6.7.5-7 and earlier allows remote attackers to cause a denial of service (infinite loop and hang) via a crafted image whose IFD contains IOP tags that all reference the beginning of the IDF. ImageMagick v6.7.5-7 y anteriores permite a atacantes remotos causar una denegación de servicio (bucle infinito y bloqueo) a través de una imagen hecha a mano, cuya IFD contiene etiquetas IOP que referencian al principio del IDF. • 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-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
CVE-2012-0867 – postgresql: MITM due improper x509_v3 CN validation during certificate verification
https://notcve.org/view.php?id=CVE-2012-0867
PostgreSQL 8.4.x before 8.4.11, 9.0.x before 9.0.7, and 9.1.x before 9.1.3 truncates the common name to only 32 characters when verifying SSL certificates, which allows remote attackers to spoof connections when the host name is exactly 32 characters.

CVE-2011-3193 – qt/harfbuzz buffer overflow
https://notcve.org/view.php?id=CVE-2011-3193
Heap-based buffer overflow in the Lookup_MarkMarkPos function in the HarfBuzz module (harfbuzz-gpos.c), as used by Qt before 4.7.4 and Pango, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted font file. Desbordamiento de buffer de memoria dinámica en la función Lookup_MarkMarkPos del módulo HarfBuzz (harfbuzz-gpos.c), tal como se usa en Qt anteriores a 4.7.4 y Pango.

https://notcve.org/view.php?id=CVE-2011-2519
Xen in the Linux kernel, when running a guest on a host without hardware assisted paging (HAP), allows guest users to cause a denial of service (invalid pointer dereference and hypervisor crash) via the SAHF instruction. Xen en el kernel de Linux, al ejecutar como invitado en una máquina sin paginación asistida por hardware (HAP), permite a usuarios invitados causar denegación de servicio (referencia a puntero inválido y caída del hipervisor) a través de la instrucción SAHF. • http://rhn.redhat.com/errata/RHSA-2011-1212.html http://www.openwall.com/lists/oss-security/2011/08/30/1 http://xenbits.xen.org/hg/xen-3.1-testing.hg/rev/15644 https://bugzilla.redhat.com/show_bug.cgi?id=718882 https://access.redhat.com/security/cve/CVE-2011-2519 • CWE-476: NULL Pointer Dereference •
CVE-2011-3389 – HTTPS: block-wise chosen-plaintext attack against SSL/TLS (BEAST)
https://notcve.org/view.php?id=CVE-2011-3389
The SSL protocol, as used in certain configurations in Microsoft Windows and Microsoft Internet Explorer, Mozilla Firefox, Google Chrome, Opera, and other products, encrypts data by using CBC mode with chained initialization vectors, which allows man-in-the-middle attackers to obtain plaintext HTTP headers via a blockwise chosen-boundary attack (BCBA) on an HTTPS session, in conjunction with JavaScript code that uses (1) the HTML5 WebSocket API, (2) the Java URLConnection API, or (3) the Silverlight WebClient API, aka a "BEAST" attack. El protocolo SSL, como se utiliza en ciertas configuraciones en Microsoft Windows y Microsoft Internet Explorer, Mozilla Firefox, Google Chrome, Opera y otros productos, cifra los datos mediante el uso del modo CBC con vectores de inicialización encadenados, lo que permite a atacantes man-in-the-middle obtener cabeceras HTTP en texto plano a través de un ataque blockwise chosen-boundary (BCBA) en una sesión HTTPS, junto con el código de JavaScript que usa (1) la API WebSocket HTML5, (2) la API Java URLConnection o (3) la API Silverlight WebClient, también conocido como un ataque "BEAST". • http://blog.mozilla.com/security/2011/09/27/attack-against-tls-protected-communications http://blogs.technet.com/b/msrc/archive/2011/09/26/microsoft-releases-security-advisory-2588513.aspx http://blogs.technet.com/b/srd/archive/2011/09/26/is-ssl-broken-more-about-security-advisory-2588513.aspx http://curl.haxx.se/docs/adv_20120124B.html http://downloads.asterisk.org/pub/security/AST-2016-001.html http://ekoparty.org/2011/juliano-rizzo.php http://eprint.iacr.org/2004/111 http: • CWE-326: Inadequate Encryption Strength •
