Official Description
The Rules Service in Websense Email Security before 7.1 allows remote attackers to cause a denial of service (service crash) via an attachment with a crafted size.
Technical Analysis
CVE-2009-5130 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
From a weakness classification perspective (CWE-119): Buffer overflow vulnerabilities can lead to arbitrary code execution or denial of service by corrupting adjacent memory.
