Vulnerability Assessment Details
Check for the version of the kernel package
Detailed Explanation for this Vulnerability Assessment
The remote host is missing the patch for the advisory MDKSA-2003:074 (kernel).
Multiple vulnerabilities were discovered and fixed in the Linux kernel.
* CVE-2003-0001: Multiple ethernet network card drivers do not pad frames with
null bytes which permits remote attackers to obtain information from previous
packets or kernel memory by using special malformed packets.
* CVE-2003-0244: The route cache implementation in the 2.4 kernel and the
Netfilter IP conntrack module permits remote attackers to cause a Denial of
Service (DoS) via CPU consumption due to packets with forged source addresses
that cause a large number of hash table collisions related to the PREROUTING
* CVE-2003-0246: The ioperm implementation in 2.4.20 and earlier kernels does
not properly restrict rights, which permits local users to gain read or write
access to certain I/O ports.
* CVE-2003-0247: A vulnerability in the TTY layer of the 2.4 kernel permits
attackers to cause a kernel oops resulting in a DoS.
* CVE-2003-0248: The mxcsr code in the 2.4 kernel permits attackers to modify CPU
state registers via a malformed address.
* CVE-2003-0462: A file read race existed in the execve() system call.
Kernels for 9.1/x86 are also available (see MDKSA-2003:066).
MandrakeSoft encourages all users to upgrade to these new kernels.
