Categoría:	Red Hat Local Security Checks
Título:	RedHat Security Advisory RHSA-2002:263
Resumen:	NOSUMMARY
Descripción:	Description: The remote host is missing updates announced in advisory RHSA-2002:263. The kernel in Red Hat Linux Advanced Server 2.1 is vulnerable to a local denial of service attack. Updated packages are available which address this vulnerability. [Updated 28 August 2003] Added CVE-2003-0461 to the list of security issues that were fixed by this advisory (there are no changes to the packages themselves). The Linux kernel handles the basic functions of the operating system. A vulnerability in the Linux kernel has been discovered in which a non-root user can cause the machine to freeze. This kernel addresses the vulnerability. Note: This bug is specific to the x86 architecture kernels only, and does not affect ia64 or other architectures. In addition, /proc/tty/driver/serial reveals the exact number of characters used in serial links, which could allow local users to obtain potentially sensitive information such as password lengths. All users should upgrade to these errata packages, which are not vulnerable to these issues. Thanks go to Christopher Devine for reporting the vulnerability on Bugtraq, and Petr Vandrovec for being the first to supply a fix to the community. Solution: Please note that this update is available via Red Hat Network. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date http://rhn.redhat.com/errata/RHSA-2002-263.html http://online.securityfocus.com/archive/1/299687/2002-11-11/2002-11-17/0 Risk factor : Medium CVSS Score: 2.1
