Descriptions
The socket implementation in net/core/sock.c in the Linux kernel before 2.6.34 does not properly manage a backlog of received packets, which allows remote attackers to cause a denial of service (memory consumption) by sending a large amount of network traffic, as demonstrated by netperf UDP tests.
La implementación del socket en net/core/sock.c en el kernel de Linux anterior a v2.6.34 no maneja correctamente un retraso de los paquetes recibidos, que permite a atacantes remotos provocar una denegación de servicio (consumo de memoria) mediante el envío de una gran cantidad de la red tráfico, como lo demuestran las pruebas netperf UDP.
The kernel packages contain the Linux kernel, the core of any Linux operating system. This update includes backported fixes for security issues. These issues, except for CVE-2011-1182, only affected users of Red Hat Enterprise Linux 6.0 Extended Update Support as they have already been addressed for users of Red Hat Enterprise Linux 6 in the 6.1 update, RHSA-2011:0542. Security fixes: Buffer overflow flaws were found in the Linux kernel's Management Module Support for Message Passing Technology based controllers. A local, unprivileged user could use these flaws to cause a denial of service, an information leak, or escalate their privileges. Various other issues were also addressed.
