Mandrake A number of vulnerabilities were discovered and corrected in the Linux 2.6 kernel.
 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.
