CVE-2011-3477 — Symantec Backup Exec System Recovery security vulnerability

Medium CVSS 5.5

GEAR Software CD DVD Filter driver (aka GEARAspiWDM.sys), as used in Symantec Backup Exec System Recovery 8.5 and BESR 2010, Symantec System Recovery 2011, Norton 360, and Norton Ghost, allows local users to cause a denial of service (system crash) via unspecified vectors.

Matched remediation archetype

Resource exhaustion and denial of service

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Identify attacker-influenced work factors including input size, nesting, compression, fan-out, regex cost, allocation, recursion, retries, and connection lifetime.
  • Map per-request and shared CPU, memory, disk, descriptor, thread, queue, and downstream-service limits.
  • Determine whether authentication, tenancy, quotas, and rate controls apply before expensive processing begins.

Remediate safely

  • Bound input size, nesting, expansion, work, concurrency, queue depth, retries, and execution time before resource-intensive processing.
  • Release resources on every success, error, cancellation, and timeout path and use backpressure instead of unbounded buffering.
  • Update affected components and add small deterministic tests that assert resource ceilings rather than exhausting a host.
