Scientific Linux Security Update : kernel on SL4.x i386/x86_64

Medium Nessus Plugin ID 60497

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

- a flaw was found in the Linux kernel's Direct-IO implementation. This could have allowed a local unprivileged user to cause a denial of service.
(CVE-2007-6716, Important)

- when running ptrace in 31-bit mode on an IBM S/390 or IBM System z kernel, a local unprivileged user could cause a denial of service by reading from or writing into a padding area in the user_regs_struct32 structure.
(CVE-2008-1514, Important)

- the do_truncate() and generic_file_splice_write() functions did not clear the setuid and setgid bits. This could have allowed a local unprivileged user to obtain access to privileged information. (CVE-2008-4210, Important)

- Tobias Klein reported a missing check in the Linux kernel's Open Sound System (OSS) implementation. This deficiency could have led to an information leak.
(CVE-2008-3272, Moderate)

- a potential denial of service attack was discovered in the Linux kernel's PWC USB video driver. A local unprivileged user could have used this flaw to bring the kernel USB subsystem into the busy-waiting state.
(CVE-2007-5093, Low)

- the ext2 and ext3 file systems code failed to properly handle corrupted data structures, leading to a possible local denial of service issue when read or write operations were performed. (CVE-2008-3528, Low)

In addition, these updated packages fix the following bugs :

- when using the CIFS 'forcedirectio' option, appending to an open file on a CIFS share resulted in that file being overwritten with the data to be appended.

- a kernel panic occurred when a device with PCI ID 8086:10c8 was present on a system with a loaded ixgbe driver.

- due to an aacraid driver regression, the kernel failed to boot when trying to load the aacraid driver and printed the following error message: 'aac_srb:
aac_fib_send failed with status: 8195'.

- due to an mpt driver regression, when RAID 1 was configured on Primergy systems with an LSI SCSI IME 53C1020/1030 controller, the kernel panicked during boot.

- the mpt driver produced a large number of extraneous debugging messages when performing a 'Host reset' operation.

- due to a regression in the sym driver, the kernel panicked when a SCSI hot swap was performed using MCP18 hardware.

- all cores on a multi-core system now scale their frequencies in accordance with the policy set by the system's CPU frequency governor.

- the netdump subsystem suffered from several stability issues. These are addressed in this updated kernel.

- under certain conditions, the ext3 file system reported a negative count of used blocks.

- reading /proc/self/mem incorrectly returned 'Invalid argument' instead of 'input/output error' due to a regression.

- under certain conditions, the kernel panicked when a USB device was removed while the system was busy accessing the device.

- a race condition in the kernel could have led to a kernel crash during the creation of a new process.

Solution

Update the affected packages.
