CVE-2019-14941Public exploitNetwork attack vector

Remote service interruption via unchecked packet length

Published Apr 27, 2020 · Updated Aug 5, 2024

Resource-exhaustion DoS in SHAREit 4.0.6.177 and earlier allows remote attackers to interrupt its service via a crafted network packet. The unsecured Windows channel treats the body-length value in a received packet header as an allocation size without enforcing a maximum. Unauthenticated network access to the listening TCP service is sufficient; the published request forces about 800 MB of allocation, exhausting memory without reported data exposure or modification.
