CVE-2005-1770: Buffer overflow in the Aavmker4 device driver in Avast!

Buffer overflow in the Aavmker4 device driver in Avast! Antivirus 4.6 and possibly other versions allows local users to cause a denial of service (system crash) and possibly execute arbitrary code via certain signals combined with crafted input.

Security readout for executives and security teams

CVE-2005-1770 is a legacy Avast! Antivirus driver flaw. A local user could trigger a system crash and may be able to run code by abusing crafted input to the Aavmker4 driver. The available record is old and sparse, so scope and fixed versions are not clearly established. Exposure is most likely limited to endpoints still running Avast! Antivirus 4.6 or similar legacy builds with the Aavmker4 driver installed. Modern managed environments are unlikely to be exposed unless they retain old systems, images, or unmanaged workstations. This is mainly a legacy exposure issue. It should not displace urgent internet-facing risks unless old Avast installations remain in production. If present, remove or replace quickly because kernel-driver crashes can disrupt endpoints and possible code execution raises privilege risk. Mitigation focus: Inventory endpoints for Avast! Antivirus 4.6 or the Aavmker4 driver.; Check Avast or Alwil guidance for fixed or unaffected versions.; Replace unsupported legacy antivirus versions with supported endpoint protection..
