-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDKSA-2006:116 http://www.mandriva.com/security/ _______________________________________________________________________ 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.
