Test Kennung:1.3.6.1.4.1.25623.1.0.51091
Kategorie:Red Hat Local Security Checks
Titel:RedHat Security Advisory RHSA-2003:416
Zusammenfassung:NOSUMMARY
Beschreibung:Description:

The remote host is missing updates announced in
advisory RHSA-2003:416.

The Linux kernel handles the basic functions of the operating system.

Paul Starzetz discovered a flaw in bounds checking in mremap() in the Linux
kernel versions 2.4.23 and previous which may allow a local attacker to
gain root privileges. No exploit is currently available
however, it is
believed that this issue is exploitable (although not trivially.) The
Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned
the name CVE-2003-0985 to this issue.

All users of Red Hat Enterprise Linux 3 are advised to upgrade to these
errata packages, which contain a backported security patch that corrects
this issue.

Red Hat would like to thank Paul Starzetz from ISEC for disclosing this
issue as well as Andrea Arcangeli and Solar Designer for working on the patch.

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

Risk factor : High

CVSS Score:
7.2
