 Package : kernel
 Date    : July 13, 2006
 Affected: 2006.0

 Problem Description:
 
 A number of vulnerabilities were discovered and corrected in the Linux
 2.6 kernel:
 
 The kernel did not clear sockaddr_in.sin_zero before returning IPv4
 socket names for the getsockopt function, which could allow a local
 user to obtain portions of potentially sensitive memory if getsockopt()
 is called with SO_ORIGINAL_DST (CVE-2006-1343).
 
 Prior to 2.6.16, a buffer overflow in the USB Gadget RNDIS
 implementation could allow a remote attacker to cause a Denial of
 Service via a remote NDIS response (CVE-2006-1368).
 
 Prior to 2.6.13, local users could cause a Denial of Service (crash)
 via a dio transfer from the sg driver to memory mapped IO space
 (CVE-2006-1528).
 
 Prior to and including 2.6.16, the kernel did not add the appropriate
 LSM file_permission hooks to the readv and writev functions, which
 could allow an attacker to bypass intended access restrictions
 (CVE-2006-1856).
 
 Prior to 2.6.16.17, a buffer oveflow in SCTP could allow a remote
 attacker to cause a DoS (crash) and possibly execute arbitrary code
 via a malformed HB-ACK chunk (CVE-2006-1857).
 
 Prior to 2.6.16.17, SCTP could allow a remote attacker to cause a DoS
 (crash) and possibly execute arbitrary code via a chunk length that is
 inconsistent with the actual length of provided parameters
 (CVE-2006-1858).
 
 Prior to 2.6.16.16, a memory leak in fs/locks.c could allow an attacker
 to cause a DoS (memory consumption) via unspecified actions
 (CVE-2006-1859).
 
 Prior to 2.6.16.16, lease_init in fs/locks.c could allow an attacker to
 cause a DoS (fcntl_setlease lockup) via certain actions (CVE-2006-1860).
 
 Prior to 2.6.17, SCTP allowed remote attackers to cause a DoS (infinite
 recursion and crash) via a packet that contains two or more DATA
 fragments (CVE-2006-2274).
 
 Prior to 2.6.16.21, a race condition in run_posix_cpu timers could allow
 a local user to cause a DoS (BUG_ON crash) by causing one CPU to attach
 a timer to a process that is exiting (CVE-2006-2445).
 
 Prior to 2.6.17.1, xt_sctp in netfilter could allow an attacker to cause
 a DoS (infinite loop) via an SCTP chunk with a 0 length (CVE-2006-3085).
 
 As well, an issue where IPC could hit an unmapped vmalloc page when
 near the page boundary has been corrected.
 
 In addition to these security fixes, other fixes have been included
 such as:   
 
 - avoid automatic update of kernel-source without updating the kernel
 - fix USB EHCI handoff code, which made some machines hang while
   booting
 - disable USB_BANDWIDTH which corrects a known problem in some USB
   sound devices
 - fix a bluetooth refcounting bug which could hang the machine
 - fix a NULL pointer dereference in USB-Serial's serial_open()
   function
 - add missing wakeup in pl2303 TIOCMIWAIT handling
 - fix a possible user-after-free in USB-Serial core
 - suspend/resume fixes
 - HPET timer fixes
 - prevent fixed button event to reach userspace on S3 resume
 - add sysfs support in ide-tape
 - fix ASUS P5S800 reboot
 
 Finally, a new drbd-utils package is provided that is a required
 upgrade with this new kernel due to a logic bug in the previously
 shipped version of drbd-utils that could cause a kernel panic on
 the master when a slave went offline.
 
 The provided packages are patched to fix these vulnerabilities.  All
 users are encouraged to upgrade to these updated kernels.
