Synopsis
A buffer overflow in noip-updater can lead to arbitrary code execution.
Background
noip-updater is a tool used for updating IP addresses of dynamic DNS records at no-ip.com.
Affected packages
Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-dns/noip-updater < 2.1.9 >= 2.1.9
Description
xenomuta found out that the GetNextLine() function in noip2.c misses a length check, leading to a stack-based buffer overflow.
Impact
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.
Workaround
There is no known workaround at this time.
Resolution
All noip-updater users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-dns/noip-updater-2.1.9"
