CVSS: 4.3EPSS: 0%CPEs: 24EXPL: 0CVE-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 •

The Network Lock Manager (NLM) protocol implementation in the NFS client functionality in the Linux kernel before 3.0 allows local users to cause a denial of service (system hang) via a LOCK_UN flock system call. La implementación del protocolo Network Lock Manager (NLM) en la funcionalidad de cliente NFS en el kernel de Linux anteriores a v3.0 permite a usuarios locales provocar una denegación de servicio (caída del sistema) a través de una llamada de sistema flock LOCK_UN. • http://ftp.osuosl.org/pub/linux/kernel/v3.0/ChangeLog-3.0 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=0b760113a3a155269a3fba93a409c640031dd68f http://rhn.redhat.com/errata/RHSA-2011-1212.html http://www.openwall.com/lists/oss-security/2011/06/23/6 https://bugzilla.redhat.com/show_bug.cgi?id=709393 https://github.com/torvalds/linux/commit/0b760113a3a155269a3fba93a409c640031dd68f https://access.redhat.com/security/cve/CVE-2011-2491 • CWE-400: Uncontrolled Resource Consumption •

The gfs2_fallocate function in fs/gfs2/file.c in the Linux kernel before 3.0-rc1 does not ensure that the size of a chunk allocation is a multiple of the block size, which allows local users to cause a denial of service (BUG and system crash) by arranging for all resource groups to have too little free space. La función gfs2_fallocate en fs/gfs2/file.c en el kernel de Linux anterior a v3.0-rc1 no garantiza que el tamaño de un trozo de asignación sea un múltiplo del tamaño de bloque, lo que permite a usuarios locales provocar una denegación de servicio (BUG y caída del sistema) mediante la organización de todos los grupos de recursos para tener un espacio libre muy reducido. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=6905d9e4dda6112f007e9090bca80507da158e63 http://marc.info/?l=bugtraq&m=139447903326211&w=2 http://rhn.redhat.com/errata/RHSA-2011-1065.html http://secunia.com/advisories/45193 http://securitytracker.com/id?1025776 http://www.kernel.org/pub/linux/kernel/v3.0/testing/ChangeLog-3.0-rc1 http://www.openwall.com/lists/oss-security/2011/07/13/1 http://www.securityfocus.com/bid/48677 https://bu • CWE-400: Uncontrolled Resource Consumption •
