noip-updater: Execution of arbitrary code A buffer overflow in noip-updater can lead to arbitrary code execution. noip-updater 2009-01-18 2009-01-18: 01 248709 remote 2.1.9 2.1.9

noip-updater is a tool used for updating IP addresses of dynamic DNS records at no-ip.com.

xenomuta found out that the GetNextLine() function in noip2.c misses a length check, leading to a stack-based buffer overflow.

A remote attacker could exploit this vulnerability to execute arbitrary code by sending a specially crafted HTTP message to the client. NOTE: Successful exploitation requires a man in the middle attack, a DNS spoofing attack or a compromise of no-ip.com servers.

There is no known workaround at this time.

All noip-updater users should upgrade to the latest version:

# emerge --sync # emerge --ask --oneshot --verbose ">=net-dns/noip-updater-2.1.9"
