Posted by Philipp Esselbach on: 07/21/2005 03:55 AM [ Print | 0 comment(s) ]
New dnsmasq packages are available for Slackware 10.0, 10.1, and -current to fix security issues. An off-by-one overflow vulnerability may allow a DHCP client to create a denial of service condition. Additional code was also added to detect and defeat attempts to poison the DNS cache.
More details about these issues may be found in the Common
Vulnerabilities and Exposures (CVE) database:
