The remote host is missing updates to the kernel announced in advisory RHSA-2009:0331. This update addresses the following security issues: * a buffer overflow was found in the Linux kernel Partial Reliable Stream Control Transmission Protocol (PR-SCTP) implementation. This could, potentially, lead to a denial of service if a Forward-TSN chunk is received with a large stream ID. (CVE-2009-0065, Important) * a memory leak was found 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) * 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 file in /sys/devices/platform/dell_rbu/. (CVE-2009-0322, Important) * a deficiency was found in the libATA implementation. This could, potentially, lead to a denial of service. Note: by default, /dev/sg* devices are accessible only to the root user. (CVE-2008-5700, Low) This update also fixes a number of non-security related bugs. For details, please visit the referenced advisories. All Red Hat Enterprise Linux 4 users should upgrade to these updated packages, which contain backported patches to resolve these issues. The system must be rebooted for this update to take effect.
