Symantec's PGP Desktop and Encryption Desktop system kernel driver is
susceptible to a local access integer overflow on all versions of Microsoft
Windows operating systems. The driver is also susceptible to a local buffer
overflow only on Microsoft Windows XP and Windows Server 2003 operating
systems. If successfully targeted these local vulnerabilities could potentially
allow arbitrary code to run with privileged access.
Product Version Build Solution
Symantec PGP Desktop 10.2.x All Symantec Encryption Desktop 10.3.0 maintenance pack 1
Symantec Encryption 10.3.0 8741 Symantec Encryption Desktop 10.3.0 maintenance pack 1
Symantec is aware of the public release of multiple vulnerabilities impacting
Symantec PGP Desktop and Symantec Encryption Desktop. The encryption kernel
driver, pgpwded.sys is susceptible to an integer overflow in the handling of
specifically malformed input that affects all Microsoft Windows operating
systems. Specifically on Windows XP and Windows Sever 2003, the kernel driver
is also susceptible to an additional buffer overflow. Both issues require
local access to a system for any attempts to target these issues. Successfully
targeting these issues could potentially result in arbitrary code running with
Symantec engineers have verified the issues and released an update addressing
them. Symantec recommends customers update to Symantec Encryption Desktop
10.3.0 maintenance pack 1 or later.
The Pre-boot Authentication in PGP Desktop and Symantec Drive Encryption
prevents the start-up level of access required for a successfully targeting of
these issues. Customers running these encryption products should be utilizing
the full protection provided by PGP Whole Disk Encryption or Symantec Drive
Customers may obtain Symantec Desktop Encryption maintenance update through
their normal Symantec support locations.
As part of normal best practices, Symantec strongly recommends:
*Restrict access to administration or management systems to privileged
*Disable remote access if not required or restrict it to trusted/authorized
*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
*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
BID: Security Focus, http://www.securityfocus.com, has assigned Bugtraq ID
(BID) to these issues for inclusion in the Security Focus vulnerability
CVE: These issues are candidates for inclusion in the CVE list
(http://cve.mitre.org), which standardizes names for security problems.
