The remote host is missing updates announced in advisory RHSA-2009:0360. The kernel-rt packages contain the Linux kernel, the core of any Linux operating system. These updated packages address the following security issues: * a memory leak exists in keyctl handling. A local, unprivileged user could use this flaw to deplete kernel memory, eventually leading to a denial of service. (CVE-2009-0031, Important) * an off-by-one underflow flaw was found in the eCryptfs subsystem. This could potentially cause a denial of service when the readlink() function returned an error. (CVE-2009-0269, Moderate) * a deficiency was found in the Remote BIOS Update (RBU) driver for Dell systems. This could allow a local, unprivileged user to cause a denial of service by reading zero bytes from the image_type or packet_size files in /sys/devices/platform/dell_rbu/. (CVE-2009-0322, Moderate) * an inverted logic flaw was found in the SysKonnect FDDI PCI adapter driver, allowing driver statistics to be reset only when the CAP_NET_ADMIN capability was absent (local, unprivileged users could reset driver statistics). (CVE-2009-0675, Moderate) * the sock_getsockopt() function in the Linux kernel did not properly initialize a data structure that can be directly returned to user-space when the getsockopt() function is called with SO_BSDCOMPAT optname set. This flaw could possibly lead to memory disclosure. (CVE-2009-0676, Moderate) For other issues addressed in this update, please visit the referenced advisories. All Red Hat Enterprise MRG users should install this update which addresses these vulnerabilities and fixes these bugs. For this update to take effect, the system must be rebooted.
