Synopsis
The remote CentOS host is missing one or more security updates.Description
Updated kernel packages that fix multiple security issues and three bugs are now available for Red Hat Enterprise Linux 4.This update has been rated as having important security impact by the Red Hat Security Response Team.
The kernel packages contain the Linux kernel, the core of any Linux operating system.
This update fixes the following security issues :
* an array index error was found in the gdth driver in the Linux kernel. A local user could send a specially crafted IOCTL request that would cause a denial of service or, possibly, privilege escalation.
(CVE-2009-3080, Important)
* a flaw was found in the collect_rx_frame() function in the HiSax ISDN driver (hfc_usb) in the Linux kernel. An attacker could use this flaw to send a specially crafted HDLC packet that could trigger a buffer out of bounds, possibly resulting in a denial of service.
(CVE-2009-4005, Important)
* permission issues were found in the megaraid_sas driver (for SAS based RAID controllers) in the Linux kernel. The 'dbg_lvl' and 'poll_mode_io' files on the sysfs file system ('/sys/') had world-writable permissions. This could allow local, unprivileged users to change the behavior of the driver. (CVE-2009-3889, CVE-2009-3939, Moderate)
* a buffer overflow flaw was found in the hfs_bnode_read() function in the HFS file system implementation in the Linux kernel. This could lead to a denial of service if a user browsed a specially crafted HFS file system, for example, by running 'ls'. (CVE-2009-4020, Low)
This update also fixes the following bugs :
* if a process was using ptrace() to trace a multi-threaded process, and that multi-threaded process dumped its core, the process performing the trace could hang in wait4(). This issue could be triggered by running 'strace -f' on a multi-threaded process that was dumping its core, resulting in the strace command hanging. (BZ#555869)
* a bug in the ptrace() implementation could have, in some cases, caused ptrace_detach() to create a zombie process if the process being traced was terminated with a SIGKILL signal. (BZ#555869)
* the RHSA-2010:0020 update resolved an issue (CVE-2009-4537) in the Realtek r8169 Ethernet driver. This update implements a better solution for that issue. Note: This is not a security regression. The original fix was complete. This update is adding the official upstream fix. (BZ#556406)
Users should upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.
