Synopsis: Important: kernel security and bug fix update
Issue date: 2010-02-02
CVE Names: CVE-2009-3080 CVE-2009-3889 CVE-2009-3939
CVE-2009-4005 CVE-2009-4020
CVE-2009-3889 CVE-2009-3939 kernel: megaraid_sas permissions in sysfs
CVE-2009-3080 kernel: gdth: Prevent negative offsets in ioctl
CVE-2009-4005 kernel: isdn: hfc_usb: fix read buffer overflow
CVE-2009-4020 kernel: hfs buffer overflow
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 kernel-2.6.9-89.0.19.EL 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)
The system must be rebooted for this update to take effect.
