The remote host is missing kernel updates announced in advisory RHSA-2009:0053. These updated packages address the following security issues: * a flaw was found in the Asynchronous Transfer Mode (ATM) subsystem. A local, unprivileged user could use the flaw to listen on the same socket more than once, possibly causing a denial of service. (CVE-2008-5079, Important) * a buffer overflow flaw was found in the libertas driver. This could, potentially, lead to a remote denial of service when an invalid beacon or probe response was received. (CVE-2008-5134, Important) * a race condition was found in the Linux kernel inotify watch removal and umount implementation. This could allow a local, unprivileged user to cause a privilege escalation or a denial of service. (CVE-2008-5182, Important) * the sendmsg() function in the Linux kernel did not block during UNIX socket garbage collection. This could, potentially, lead to a local denial of service. (CVE-2008-5300, Important) * 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 deficiency was found in the libATA implementation. This could, potentially, lead to a denial of service. By default, the /dev/sg* devices are accessible only to the root user. (CVE-2008-5700, Low) For further details on other bugs fixed, please visit the referenced security advisories.
