The remote Red Hat host is missing one or more security updates.
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 advisory includes fixes for several security issues :
iSEC Security Research discovered a VMA handling flaw in the uselib(2)
system call of the Linux kernel. A local user could make use of this
flaw to gain elevated (root) privileges. The Common Vulnerabilities
and Exposures project (cve.mitre.org) has assigned the name
CVE-2004-1235 to this issue.
A flaw was discovered where an executable could cause a VMA overlap
leading to a crash. A local user could trigger this flaw by creating a
carefully crafted a.out binary on 32-bit systems or a carefully
crafted ELF binary on Itanium systems. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CVE-2005-0003
to this issue.
iSEC Security Research discovered a flaw in the page fault handler
code that could lead to local users gaining elevated (root) privileges
on multiprocessor machines. The Common Vulnerabilities and Exposures
project (cve.mitre.org) has assigned the name CVE-2005-0001 to this
issue. A patch that coincidentally fixed this issue was committed to
the Update 4 kernel release in December 2004. Therefore Red Hat
Enterprise Linux 3 kernels provided by RHBA-2004:550 and subsequent
updates are not vulnerable to this issue.
A flaw in the system call filtering code in the audit subsystem
included in Red Hat Enterprise Linux 3 allowed a local user to cause a
crash when auditing was enabled. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CVE-2004-1237
to this issue.
Olaf Kirch discovered that the recent security fixes for cmsg_len
handling (CVE-2004-1016) broke 32-bit compatibility on 64-bit
platforms such as AMD64 and Intel EM64T. A patch to correct this issue
A recent Internet Draft by Fernando Gont recommended that ICMP Source
Quench messages be ignored by hosts. A patch to ignore these messages
Note: The kernel-unsupported package contains various drivers and
modules that are unsupported and therefore might contain security
problems that have not been addressed.
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.
