Description:
Lotus Domino bindsock is vulnerable to a flaw that can allow a local
attacker to gain root privileges. The problem is due to insufficient
bounds checking with the PATH environment variable. An attacker can
use a PATH that, when processed, will execute arbitrary code.

Technical Recommendation:
Upgrade with the latest version available. Lotus Domino version 5.0.9a
is not vulnerable to the issue.

Vendor Reference:
