Overview
Symantecs PGP Universal Server, under specific circumstances, may inadvertently
expose a PGP clients private key.
Product(s) Affected
Product Version Solution
PGP Universal Server 3.2.x PGP Universal Server 3.2.1 MP2
Details
Symantec became aware that in certain specific instances, the PGP Universal
Server failed to properly clear a PGP clients authenticated session at the
termination of an authorized PGP key search request. This could result in the
unauthorized exposure of that clients private key during and immediately
following an unauthenticated request from another PGP client.
Symantec Response
Symantec engineers have verified this issue and released an update addressing
it. Symantec recommends customers update to PGP Universal Server 3.2.1 MP2 or
later.
Update information
Customers may obtain Symantecs PGP Universal Server 3.2.1 MP2 update through
their normal PGP support locations.
Best Practices
As part of normal best practices, Symantec strongly recommends:
Restrict access to administration or management systems to privileged
users.
Disable remote access if not required or restrict it to trusted/authorized
systems only.
Where possible, limit exposure of application and web interfaces to
trusted/internal networks only.
Keep all operating systems and applications updated with the latest vendor
patches.
Follow a multi-layered approach to security. Run both firewall and
anti-malware applications, at a minimum, to provide multiple points of
detection and protection to both inbound and outbound threats.
Deploy network and host-based intrusion detection systems to monitor
network traffic for signs of anomalous or suspicious activity. This may
aid in detection of attacks or malicious activity related to exploitation
of latent vulnerabilities
