Date : July 5, 2006

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.
