lynx contains a flaw that may allow a malicious user to overwrite arbitrary files. The issue is due to lynx creating temporary files in the world-writeable /tmp directory. It is possible that the flaw may allow a local attacker to overwrite files with downloaded files, resulting in a loss of integrity.
Upgrade to version 2.8.5 or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
