GLSA-200901-12 : noip-updater: Execution of arbitrary code
High Nessus Plugin ID 35406
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200901-12 (noip-updater: Execution of arbitrary code)
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.
SolutionAll noip-updater users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-dns/noip-updater-2.1.9'
