[slackware-security]  dnsmasq (SSA:2005-201-01)


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:
