CVE-2016-9429
HighSummary
An issue was discovered in w3m before version 0.5.3-31 related to a buffer overflow in the formUpdateBuffer function. Remote attackers can cause a denial of service (crash) and possibly execute arbitrary code via a crafted HTML page.
Risk Assessment
Organizations may be exposed to attacks that lead to system crashes and allow unauthorized code execution, potentially resulting in data loss or system takeover.
Recommendation
It is recommended to update w3m to version 0.5.3-31 or later to mitigate this vulnerability and reduce the risk of attacks.
