Integer underflow in the l2cap_config_req function in net/bluetooth/l2cap_core.c in the Linux kernel before 3.0 allows remote attackers to cause a denial of service (heap memory corruption) or possibly have unspecified other impact via a small command-size value within the command header of a Logical Link Control and Adaptation Protocol (L2CAP) configuration request, leading to a buffer overflow. Desbordamiento de enteros en la función l2cap_config_req en net/bluetooth/l2cap_core.c en el Kernel de Linux anterior a v3.0 permite a atacantes remotos provocar una denegación de servicio o posiblemente tner otro impacto desconocido a través de un pequeño valor "command-size" dentro del comando header en un "Control de Enlace Lógico" (Logical Link Control) y petición de configuración de "Protocolo de Adaptación" (Adaptation Protocol (L2CAP)), cargando un desbordamiento de bufer. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=7ac28817536797fd40e9646452183606f9e17f71 http://marc.info/?l=linux-kernel&m=130891911909436&w=2 http://securityreason.com/securityalert/8359 http://www.kernel.org/pub/linux/kernel/v3.0/ChangeLog-3.0 http://www.openwall.com/lists/oss-security/2011/06/24/9 http://www.openwall.com/lists/oss-security/2011/06/27/3 http://www.osvdb.org/74679 http://www.securityfocus.com/bid/48472 https:/&#x • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-191: Integer Underflow (Wrap or Wraparound) •
