GLSA-200909-15 : Lynx: Arbitrary command execution
Critical Nessus Plugin ID 40962
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200909-15 (Lynx: Arbitrary command execution)
Clint Ruoho reported that the fix for CVE-2005-2929 (GLSA 200511-09) only disabled the lynxcgi:// handler when not using the advanced mode.
A remote attacker can entice a user to access a malicious HTTP server, causing Lynx to execute arbitrary commands. NOTE: The advanced mode is not enabled by default. Successful exploitation requires the 'lynxcgi://' protocol to be registered with lynx on the victim's system.
There is no known workaround at this time.
SolutionAll Lynx users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=www-client/lynx-2.8.6-r4'
