CVE-2019-3971 (GCVE-0-2019-3971)

Vulnerability from cvelistv5 – Published: 2019-07-17 20:35 – Updated: 2024-08-04 19:26

Summary

Comodo Antivirus versions up to 12.0.0.6810 are vulnerable to a local Denial of Service affecting CmdVirth.exe via its LPC port "cmdvrtLPCServerPort". A low privileged local process can connect to this port and send an LPC_DATAGRAM, which triggers an Access Violation due to hardcoded NULLs used for Source parameter in a memcpy operation that is called for this handler. This results in CmdVirth.exe and its child svchost.exe instances to terminate.

Severity

No CVSS data available.
