Description Preview

The installation of Sophos PureMessage for Microsoft Exchange 3.0 before 3.0.2, when both anti-virus and anti-spam are supported, does not create or launch the associated scan engines when the system is under heavy load, which has unspecified impact, probably remote bypass of scanner protection or a denial of service (message loss or delay).

Overview

This CVE describes a flaw in Sophos PureMessage for Microsoft Exchange in versions prior to 3.0.2 where the scan engines fail to be created or started under heavy load when antivirus and anti-spam features are enabled. The impact is not explicitly defined, but it is likely to involve a remote bypass of scanner protection or a denial of service manifested as message loss or delay.

Remediation

  • Upgrade to Sophos PureMessage for Microsoft Exchange 3.0.2 or later where the issue is fixed.
  • If immediate upgrade is not possible, contact Sophos support for a potential workaround or mitigation and request guidance on temporarily mitigating heavy-load scenarios.
  • After updating, verify that the antivirus and anti-spam scan engines initialize and operate normally under simulated high-load conditions.
  • Implement monitoring and alerting to detect scan-engine startup failures or delays, and establish a plan to scale resources during peak loads.
  • Plan for a staged rollout and conduct testing in a non-production environment before applying the fix across production systems.
