Mandriva Linux Security Advisory MDKSA-2006:116

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

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, 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

Prior to, 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

Prior to, 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

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

The provided packages are patched to fix these vulnerabilities. All
users are encouraged to upgrade to these updated kernels.
