- CVEs with nessus.description==This update addresses the following security issues :
- 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)
- when fput() was called to close a socket, the
__scm_destroy() function in the Linux kernel could make indirect recursive calls to itself. This could, potentially, lead to a local denial of service.
(CVE-2008-5029, Important)
- a deficiency was found in the Linux kernel virtual file system (VFS) implementation. This could allow a local, unprivileged user to make a series of file creations within deleted directories, possibly causing a denial of service. (CVE-2008-3275, Moderate)
- a buffer underflow flaw was found in the Linux kernel IB700 SBC watchdog timer driver. This deficiency could lead to a possible information leak. By default, the '/dev/watchdog' device is accessible only to the root user. (CVE-2008-5702, Low)
- the hfs and hfsplus file systems code failed to properly handle corrupted data structures. This could, potentially, lead to a local denial of service.
(CVE-2008-4933, CVE-2008-5025, Low)
- a flaw was found in the hfsplus file system implementation. This could, potentially, lead to a local denial of service when write operations were performed.
(CVE-2008-4934, Low)
This update also fixes the following bugs :
- when running Red Hat Enterprise Linux 4.6 and 4.7 on some systems running Intel® CPUs, the cpuspeed daemon did not run, preventing the CPU speed from being changed, such as not being reduced to an idle state when not in use.
- mmap() could be used to gain access to beyond the first megabyte of RAM, due to insufficient checks in the Linux kernel code. Checks have been added to prevent this.
- attempting to turn keyboard LEDs on and off rapidly on keyboards with slow keyboard controllers, may have caused key presses to fail.
- after migrating a hypervisor guest, the MAC address table was not updated, causing packet loss and preventing network connections to the guest. Now, a gratuitous ARP request is sent after migration. This refreshes the ARP caches, minimizing network downtime.
- writing crash dumps with diskdump may have caused a kernel panic on Non-Uniform Memory Access (NUMA) systems with certain memory configurations.
- on big-endian systems, such as PowerPC, the getsockopt() function incorrectly returned 0 depending on the parameters passed to it when the time to live (TTL) value equaled 255, possibly causing memory corruption and application crashes.
- a problem in the kernel packages provided by the RHSA-2008:0508 advisory caused the Linux kernel's built-in memory copy procedure to return the wrong error code after recovering from a page fault on AMD64 and Intel 64 systems. This may have caused other Linux kernel functions to return wrong error codes.
- a divide-by-zero bug in the Linux kernel process scheduler, which may have caused kernel panics on certain systems, has been resolved.
- the netconsole kernel module caused the Linux kernel to hang when slave interfaces of bonded network interfaces were started, resulting in a system hang or kernel panic when restarting the network.
- the '/proc/xen/' directory existed even if systems were not running Red Hat Virtualization. This may have caused problems for third-party software that checks virtualization-ability based on the existence of '/proc/xen/'. Note: this update will remove the '/proc/xen/' directory on systems not running Red Hat Virtualization.
This updated kernel-utils package adds an enhancement in the way of proper support for user-space frequency-scaling on multi-core systems
