CVE-2010-4249

La función wait_for_unix_gc de net/unix/garbage.c en el kernel de Linux en versiones anteriores a la 2.6.37-rc3-next-20101125 no selecciona apropiadamente el momento de recolectar la basura de los sockets en uso; lo que permite, a usuarios locales, provocar una denegación de servicio (cuelgue del sistema) a través del uso modificado de las llamadas al sistema "socketpair" y "sendmsg" de los sockets SOCK_SEQPACKET.

Nelson Elhage discovered that the kernel did not correctly handle process cleanup after triggering a recoverable kernel bug. Nelson Elhage discovered that Econet did not correctly handle AUN packets over UDP. Dan Rosenberg discovered that the OSS subsystem did not handle name termination correctly. Dan Rosenberg discovered that IRDA did not correctly check the size of buffers. Dan Carpenter discovered that the TTPCI DVB driver did not check certain values during an ioctl. Jens Kuehnel discovered that the InfiniBand driver contained a race condition. Timo Warns discovered that the LDM disk partition handling code did not correctly handle certain values.
