CVE-2018-6198 (opens in a new tab)How to fix?
There is no fixed version for RHEL:6 w3m-img.
NVD Description
Note: Versions mentioned in the description apply only to the upstream w3m-img package and not the w3m-img package as distributed by RHEL.
See How to fix? for RHEL:6 relevant fixed versions and status.
w3m through 0.5.3 does not properly handle temporary files when the ~/.w3m directory is unwritable, which allows a local attacker to craft a symlink attack to overwrite arbitrary files.
