Unauthenticated code execution via out-of-bounds write
Published Feb 11, 2021 · Updated Aug 3, 2024
Out-of-bounds write in Teradici PCoIP Soft Client 20.10.0 and earlier allows remote attackers to execute code over a network. Teradici has not published the affected parser, input field, or memory operation beyond stating that the client performs an out-of-bounds write. No authentication or user interaction is required, and successful exploitation executes attacker-controlled code in the client process.
