Description

New ntp packages are available for Slackware 8.1, 9.0, 9.1, 10.0, 10.1, 10.2, 11.0, 12.0, 12.1, 12.2, 13.0, and -current to fix a security issue. If a spoofed mode 7 packet is sent to a vulnerable NTP daemon it may cause CPU and/or disk space exhaustion, resulting in a denial of service.

More details about this issue may be found in the Common Vulnerabilities and Exposures (CVE) database:

HINT: Getting slow download speeds from ftp.slackware.com? Give slackware.osuosl.org a try. This is another primary FTP site for Slackware that can be considerably faster than downloading directly from ftp.slackware.com.

Thanks to the friendly folks at the OSU Open Source Lab (http://osuosl.org) for donating additional FTP and rsync hosting to the Slackware project! :-)

Also see the "Get Slack" section on http://slackware.com for additional mirror sites near you.
