Título:	RedHat Security Advisory RHSA-2010:0704
Resumen:	NOSUMMARY
Descripción:	Description: The remote host is missing updates announced in advisory RHSA-2010:0704. The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issue: * The compat_alloc_user_space() function in the Linux kernel 32/64-bit compatibility layer implementation was missing sanity checks. This function could be abused in other areas of the Linux kernel if its length argument can be controlled from user-space. On 64-bit systems, a local, unprivileged user could use this flaw to escalate their privileges. (CVE-2010-3081, Important) Red Hat would like to thank Ben Hawkes for reporting this issue. Red Hat is aware that a public exploit for this issue is available. Refer to Knowledgebase article DOC-40265 for further details: https://access.redhat.com/kb/docs/DOC-40265 Users should upgrade to these updated packages, which contain a backported patch to correct this issue. The system must be rebooted for this update to take effect. Solution: Please note that this update is available via Red Hat Network.
