"Updated kernel packages that address various security vulnerabilities
are now available for Red Hat Enterprise Linux.
The Linux kernel handles the basic functions of the operating system.
Security issues have been found that affect the versions of the Linux
kernel shipped with Red Hat Enterprise Linux :
CVE-2003-0462: Paul Starzetz discovered a file read race condition
existing in the execve() system call, which could cause a local crash.
CVE-2003-0501: The /proc filesystem in Linux allows local users to
obtain sensitive information by opening various entries in /proc/self
before executing a setuid program. This causes the program to fail to
change the ownership and permissions of already opened entries.
CVE-2003-0550: The STP protocol is known to have no security, which
could allow attackers to alter the bridge topology. STP is now turned
off by default.
CVE-2003-0551: STP input processing was lax in its length checking,
which could lead to a denial of service (DoS).
CVE-2003-0552: Jerry Kreuscher discovered that the Forwarding table
could be spoofed by sending forged packets with bogus source addresses
the same as the local host.
CVE-2003-0619: An integer signedness error in the decode_fh function
of nfs3xdr.c allows remote attackers to cause a denial of service
(kernel panic) via a negative size value within XDR data of an NFSv3
procedure call.
CVE-2003-0699: The C-Media PCI sound driver in Linux kernel versions
prior to 2.4.21 accesses userspace without using the get_user
function, which is a potential security hole.
All users are advised to upgrade to these erratum packages, which
contain backported security patches correcting these vulnerabilities."
