 Problem Description:
 
 A number of vulnerabilities have been discovered and corrected in the
 Linux 2.4 kernel:
 
 A numeric casting discrepancy in sdla_xfer could allow a local user to
 read portions of kernel memory via a large len argument
 (CVE-2004-2607).
 
 The traps.c file executes stack segment faults on an exception stack,
 which could allow a local user to cause an oops and stack fault
 exception (CVE-2005-1767).
 
 The find_target function in ptrace32.c does not properly handle a NULL
 return value from another function, allowing local users to cause a
 kernel crash/oops by running a 32-bit ltrace program with the -i option
 on a 64-bit executable program (CVE-2005-2553).
 
 A race condition in ip_vs_conn_flush, when running on SMP systems,
 could allow a local attacker to cause null dereference DoS by causing
 a connection timer to expire while the connection table is being
 flushed before the appropriate lock is acquired (CVE-2005-3274).
 
 The NAT code in ip_nat_proto_tcp.c and ip_nat_proto_udp.c incorrectly
 declares a variable to be static, which could allow a remote attacker
 to cause a Denial of Service via memory corruption by causing two
 packets for the same protocol to be NATed at the same time
 (CVE-2005-3275).
 
 The IPv6 flowlabel handling code modified the wrong variable in certain
 circumstances, which could allow a local user to corrupt kernel memory
 or cause a Denial of Service (crash) by triggering a free of non-
 allocated memory (CVE-2005-3806).
 
 The wan/sdla.c file does not require CAP_SYS_RAWIO privilege for an
 SDLA firmware upgrade with unknown impact and local attack vectors
 (CVE-2006-0096).
 
 The provided packages are patched to fix these vulnerabilities.  All
 users are encouraged to upgrade to these updated kernels.
 
 To update your kernel, please follow the directions located at:
