"Updated kernel packages that fix several security issues in Red Hat
Enterprise Linux 3 are now available.
The Linux kernel handles the basic functions of the operating system.
This update includes fixes for several security issues :
A missing serialization flaw in unix_dgram_recvmsg was discovered that
affects kernels prior to 2.4.28. A local user could potentially make
use of a race condition in order to gain privileges. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the
name CVE-2004-1068 to this issue.
Paul Starzetz of iSEC discovered various flaws in the ELF binary
loader affecting kernels prior to 2.4.28. A local user could use thse
flaws to gain read access to executable-only binaries or possibly gain
privileges. (CVE-2004-1070, CVE-2004-1071, CVE-2004-1072,
CVE-2004-1073)
A flaw when setting up TSS limits was discovered that affects AMD
AMD64 and Intel EM64T architecture kernels prior to 2.4.23. A local
user could use this flaw to cause a denial of service (crash) or
possibly gain privileges. (CVE-2004-0812)
An integer overflow flaw was discovered in the ubsec_keysetup function
in the Broadcom 5820 cryptonet driver. On systems using this driver, a
local user could cause a denial of service (crash) or possibly gain
elevated privileges. (CVE-2004-0619)
Stefan Esser discovered various flaws including buffer overflows in
the smbfs driver affecting kernels prior to 2.4.28. A local user may
be able to cause a denial of service (crash) or possibly gain
privileges. In order to exploit these flaws the user would require
control of a connected Samba server. (CVE-2004-0883, CVE-2004-0949)
SGI discovered a bug in the elf loader that affects kernels prior to
2.4.25 which could be triggered by a malformed binary. On
architectures other than x86, a local user could create a malicious
binary which could cause a denial of service (crash). (CVE-2004-0136)
Conectiva discovered flaws in certain USB drivers affecting kernels
prior to 2.4.27 which used the copy_to_user function on uninitialized
structures. These flaws could allow local users to read small amounts
of kernel memory. (CVE-2004-0685)
All Red Hat Enterprise Linux 3 users are advised to upgrade their
kernels to the packages associated with their machine architectures
and configurations as listed in this erratum."
