CVSS: 1.9EPSS: 0%CPEs: 10EXPL: 0CVE-2011-2492 – kernel: bluetooth: l2cap and rfcomm: fix 1 byte infoleak to userspace
https://notcve.org/view.php?id=CVE-2011-2492
The bluetooth subsystem in the Linux kernel before 3.0-rc4 does not properly initialize certain data structures, which allows local users to obtain potentially sensitive information from kernel memory via a crafted getsockopt system call, related to (1) the l2cap_sock_getsockopt_old function in net/bluetooth/l2cap_sock.c and (2) the rfcomm_sock_getsockopt_old function in net/bluetooth/rfcomm/sock.c. El subsistema de bluetooth en el kernel de Linux anteriores a v3.0-rc4 no inicializa correctamente algunas estructuras de datos, lo que permite a usuarios locales obtener información sensible de la memoria del kernel a través de una llamada getsockopt manipulada, en relación con (1) la función l2cap_sock_getsockopt_old en net/bluetooth/l2cap_sock.c y (2) la función rfcomm_sock_getsockopt_old en net/bluetooth/rfcomm/sock.c. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=8d03e971cf403305217b8e62db3a2e5ad2d6263f http://marc.info/?l=bugtraq&m=139447903326211&w=2 http://permalink.gmane.org/gmane.linux.bluez.kernel/12909 http://rhn.redhat.com/errata/RHSA-2011-0927.html http://securitytracker.com/id?1025778 http://www.kernel.org/pub/linux/kernel/v3.0/testing/ChangeLog-3.0-rc4 http://www.openwall.com/lists/oss-security/2011/06/24/2 http://www.openwall.com/lists/ • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

https://notcve.org/view.php?id=CVE-2011-2213
The inet_diag_bc_audit function in net/ipv4/inet_diag.c in the Linux kernel before 2.6.39.3 does not properly audit INET_DIAG bytecode, which allows local users to cause a denial of service (kernel infinite loop) via crafted INET_DIAG_REQ_BYTECODE instructions in a netlink message, as demonstrated by an INET_DIAG_BC_JMP instruction with a zero yes value, a different vulnerability than CVE-2010-3880. La función net_diag_bc_audit en net/ipv4/inet_diag.c en el Kernel de Linux anterior a v2.6.39.3 no audita adecuadamente bytecode INET_DIAG, lo que permite a usuarios locales provocar una denegación de servicio a través de instrucciones manipuladas INET_DIAG_REQ_BYTECODE en un mensaje netlink, como se demostró por una instrucción INET_DIAG_BC_JMP con un valor zero yes, una vulnerabilidad diferente que CVE-2010-3880. • http://article.gmane.org/gmane.linux.network/197206 http://article.gmane.org/gmane.linux.network/197208 http://article.gmane.org/gmane.linux.network/197386 http://article.gmane.org/gmane.linux.network/198809 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=eeb1497277d6b1a0a34ed36b97e18f2bd7d6de0d http://marc.info/?l=bugtraq&m=139447903326211&w=2 http://patchwork.ozlabs.org/patch/100857 http://rhn.redhat.com/errata/RHSA-2011-0927.html http://www.kern • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

net/sctp/sm_make_chunk.c in the Linux kernel before 2.6.34, when addip_enable and auth_enable are used, does not consider the amount of zero padding during calculation of chunk lengths for (1) INIT and (2) INIT ACK chunks, which allows remote attackers to cause a denial of service (OOPS) via crafted packet data. net/sctp/sm_make_chunk.c del kernel de Linux en versiones anteriores a 2.6.34, si se utiliza addip_enable y auth_enable, no considera la cantidad de "padding" durante el cálculo de la longitud para los segmentos ("chunks")(1) INIT y (2) INIT ACK, lo que permite a atacantes remotos provocar una denegación de servicio (OOPS) a través de paquetes modificados. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=a8170c35e738d62e9919ce5b109cf4ed66e95bde http://mirror.anl.gov/pub/linux/kernel/v2.6/ChangeLog-2.6.34 http://openwall.com/lists/oss-security/2011/04/11/12 http://openwall.com/lists/oss-security/2011/04/11/4 http://rhn.redhat.com/errata/RHSA-2011-0927.html https://bugzilla.redhat.com/show_bug.cgi?id=695383 https://access.redhat.com/security/cve/CVE-2011-1573 • CWE-682: Incorrect Calculation •
