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. Permite a atacantes remotos provocar una denegación de servicio (caída) y posiblemente ejecutar código arbitrario a través de un archivo de fuentes modificado. • http://cgit.freedesktop.org/harfbuzz.old/commit/?id=81c8ef785b079980ad5b46be4fe7c7bf156dbf65 http://cgit.freedesktop.org/harfbuzz/commit/src/harfbuzz-gpos.c?id=da2c52abcd75d46929b34cad55c4fb2c8892bc08 http://git.gnome.org/browse/pango/commit/pango/opentype/harfbuzz-gpos.c?id=a7a715480db66148b1f487528887508a7991dcd0 http://lists.opensuse.org/opensuse-updates/2011-10/msg00007.html http://lists.opensuse.org/opensuse-updates/2011-10/msg00008.html http://rhn.redhat.com/errata/RHSA-2011-1323.html http://rhn.redhat.com/errata/RH • CWE-787: Out-of-bounds Write •
CVE-2011-2189 – Linux Kernel 2.6.35 - Network Namespace Remote Denial of Service
https://notcve.org/view.php?id=CVE-2011-2189
net/core/net_namespace.c in the Linux kernel 2.6.32 and earlier does not properly handle a high rate of creation and cleanup of network namespaces, which makes it easier for remote attackers to cause a denial of service (memory consumption) via requests to a daemon that requires a separate namespace per connection, as demonstrated by vsftpd. net / core / net_namespace.c en el kernel de Linux v2.6.32 y anteriores no maneja adecuadamente una alta tasa de creación y limpieza de los espacios de nombres de red, lo cual lo hace más fácil para los atacantes remotos provocar una denegación de servicio (consumo de memoria) a través de peticiones a un demonio que requiere un espacio de nombres separados por conexión, como se demuestra por vsftpd. • https://www.exploit-db.com/exploits/36425 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=629373 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=2b035b39970740722598f7a9d548835f9bdd730f http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=f875bae065334907796da12523f9df85c89f5712 http://ie.archive.ubuntu.com/linux/kernel/v2.6/ChangeLog-2.6.33 http://kerneltrap.org/mailarchive/git-commits-head/2009/12/8/15289 http://neil.brown • CWE-400: Uncontrolled Resource Consumption •
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 •
CVE-2011-3192 – Apache - Denial of Service
https://notcve.org/view.php?id=CVE-2011-3192
The byterange filter in the Apache HTTP Server 1.3.x, 2.0.x through 2.0.64, and 2.2.x through 2.2.19 allows remote attackers to cause a denial of service (memory and CPU consumption) via a Range header that expresses multiple overlapping ranges, as exploited in the wild in August 2011, a different vulnerability than CVE-2007-0086. El filtro byterange en el Servidor Apache HTTP v1.3.x, v2.0.x hasta v2.0.64, y v2.2.x hasta v2.2.19 permite a tacantes remotos provocar una denegación de servicio (consumo de memoria y CPU) a través de una cabecera Range que expresa múltiple rangos de solapamiento, como se explotó en Agosto 2011, una vulnerabilidad diferente que CVE-2007-0086. • https://www.exploit-db.com/exploits/18221 https://www.exploit-db.com/exploits/17696 https://github.com/limkokholefork/CVE-2011-3192 https://github.com/futurezayka/CVE-2011-3192 http://archives.neohapsis.com/archives/fulldisclosure/2011-08/0285.html http://blogs.oracle.com/security/entry/security_alert_for_cve_2011 http://lists.apple.com/archives/Security-announce/2011//Oct/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2011-09/msg00006.html http://lists.opensuse. • CWE-400: Uncontrolled Resource Consumption •
