3. Problem description:
Buffer overflows were found in the nwclient program. An attacker, using a long -T option, could possibly execute arbitrary code and gain privileges. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-1079 to this issue.
A bug was found in the way ncpfs handled file permissions. ncpfs did not sufficiently check if the file owner matched the user attempting to access the file, potentially violating the file permissions. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2005-0013 to this issue.
A buffer overflow was found in the ncplogin program. A remote malicious NetWare server could execute arbitrary code on a victim's machine. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2005-0014 to this issue.
All users of ncpfs are advised to upgrade to this updated package, which contains backported fixes for these issues.
4. Solution:
Before applying this update, make sure all previously released errata relevant to your system have been applied.
To update all RPMs for your particular architecture, run:
rpm -Fvh [filenames]
where [filenames] is a list of the RPMs you wish to upgrade. Only those RPMs which are currently installed will be updated. Those RPMs which are not installed but included in the list will not be updated. Note that you can also use wildcards (*.rpm) if your current directory *only* contains the desired RPMs.
Please note that this update is also available via yum and apt. Many people find this an easier way to apply updates. To use yum issue:
yum update
or to use apt:
apt-get update; apt-get upgrade
This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. This assumes that you have yum or apt-get configured for obtaining Fedora Legacy content. Please visit http://www.fedoralegacy.org/docs for directions on how to configure yum and apt-get.
