- Updated kernel packages for Red Hat Enterprise Linux are now available
- which address several security vulnerabilities.
-
- The Linux kernel handles the basic functions of the operating system.
-
- Several security issues have been found that affect the Linux kernel:
-
- Al Viro found a security issue in the tty layer whereby any user could
- cause a kernel oops. The Common Vulnerabilities and Exposures project
- (cve.mitre.org) has assigned the name CAN-2003-0247 to this issue.
-
- Andrea Arcangeli found an issue in the low-level mxcsr code in which a
- malformed address would leave garbage in cpu state registers. The Common
- Vulnerabilities and Exposures project (cve.mitre.org) has assigned the
- name CAN-2003-0248 to this issue.
-
- The TCP/IP fragment reassembly handling allows remote attackers to cause a
- denial of service (CPU consumption) via packets that cause a large number
- of hash table collisions, a vulnerability similar to CAN-2003-0244. The
- Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned
- the name CAN-2003-0364 to this issue.
-
- These kernels also contain updated fixes for the ioperm security issue, as
- well as fixes for a number of bugs.
-
- It is recommended that users upgrade to these erratum kernels, which
- contain patches to correct these vulnerabilities.
