 Package : kernel
 Date    : July 5, 2006
 Affected: Corporate 3.0, Multi Network Firewall 2.0

 Problem Description:
 
 A number of vulnerabilities were discovered and corrected in the Linux
 2.6 kernel:
 
 Prior to 2.6.14, the atm module allows local users to cause a Denial of
 Service (panic) via certain socket calls that produce inconsistent
 reference counts for loadable protocol modules (CVE-2005-3359).
 
 Prior to 2.6.15, the auto-reap child processes included processes with
 ptrace attached, leading to a dangling ptrace reference and allowing
 local users to cause a Denial of Service (crash) (CVE-2005-3784).
 
 Prior to and including 2.6.12, a memory leak in the ip6_input_finish
 function could allow an attacker to cause a Denial of Service via
 malformed IPv6 packets with unspecified parameter problems, which
 prevents SKB from being freed (CVE-2005-3858).
 
 Prior to 2.6.15, a buffer overflow in sysctl could allow a local user
 to corrupt user memory and possibly cause a Denial of Service via a
 long string, causing sysctl to write a zero byte outside the buffer
 (CVE-2005-4618).
 
 Prior to 2.6.11, wan/sdla.c does not require CAP_SYS_RAWIO privilege
 for an SDLA firmware upgrade, with unknown impact and local attack
 vectors (CVE-2006-0096).
 
 Prior to 2.6.15.5, a local user could cause a Denial of Service (NFS
 client panic) via unknown attack vectors related to the use of O_DIRECT
 (direct I/O) (CVE-2006-0555).
 
 Prior to 2.6.16, the ip_push_pending_frames function increments the IP
 ID field when sending a RST after receiving unsolicited TCP SYN-ACK
 packets, which allows a remote attacker to conduct an idle scan attack,
 bypassing any intended protection against such an attack
 (CVE-2006-1242).
 
 Prior to 2.6.16.8, the ip_route_input function allows local users to
 cause a DoS (panic) via a request for a route for a multicast IP
 address, which triggers a null dereference (CVE-2006-1525).
 
 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 2.6.11.12, the choose_new_parent function includes certain
 debugging code which could allow a local user to cause a Denial of
 Service (panic) by causing certain circumstances involving termination
 of a parent process (CVE-2006-1855).
 
 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, local users can bypass IPC permissions and modify a
 read-only attachment of shared memory by using mprotect to give write
 permission to the attachment (CVE-2006-2071).
 
 Prior to 2.6.17, the ECNE chunk handling in SCTP (lksctp) allows remote
 attackers to cause a DoS (kernel panic) via an unexpected chucnk when
 the session is in CLOSED state (CVE-2006-2271).
 
 Prior to 2.6.17, SCTP (lksctp) allows remote attacker to cause a DoS
 (kernel panic) via incoming IP fragmented COOKIE_ECHO and HEARTBEAT
 SCTP control chunks (CVE-2006-2272).
 
 Memory corruption can be triggered remotely when the ip_nat_snmp_basic
 module is loaded and traffic on port 161 or 162 is NATed
 (CVE-2006-2444).
 
 The provided packages are patched to fix these vulnerabilities.  All
 users are encouraged to upgrade to these updated kernels.
