|Gentoo Linux Security Advisory
Title: noip-updater: Execution of arbitrary code (GLSA 200901-12)
Date: January 18, 2009
A buffer overflow in noip-updater can lead to arbitrary code execution.
noip-updater is a tool used for updating IP addresses of dynamic DNS records at no-ip.com.
Vulnerable: < 2.1.9
Unaffected: >= 2.1.9
Architectures: All supported architectures
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"
