[slackware-security]  ntp (SSA:2009-343-01)

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.
