The remote host is missing an update to kernel
announced via advisory MDKSA-2006:044.
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:
http://www.mandriva.com/en/security/kernelupdate
Affected: Corporate 2.1, Corporate 3.0
Solution:
To upgrade automatically use MandrakeUpdate or urpmi. The verification
of md5 checksums and GPG signatures is performed automatically for you.
