Name of the Vulnerable Software and Affected Versions w3m versions prior to 0.5.3+git20161009

Description The issue exists due to insufficient input validation in the parsetagx.c function of the w3m service. This can be exploited by a remote attacker using a specially crafted file to bypass certificate validation. Additionally, the vulnerability allows remote attackers to crash the application via a crafted HTML file related to an i tag.

Recommendations For versions prior to 0.5.3+git20161009, update to version 0.5.3+git20161009 or later to resolve the issue. As a temporary workaround, consider restricting the use of the parsetagx.c function until a patch is available. Avoid using the w3m service with untrusted HTML files until the issue is resolved.
