    CVE ID         : CVE-2022-24882 CVE-2022-39320
    Debian Bug     : 1024511 1098355

    Multiple vulnerabilties have been found in freelrdp2, a free
    implementation of the Remote Desktop Protocol (RDP) which
    potentially allows potential buffer overreads or not properly abort
    NTLM authentication on empty password, if used as server.

    Additonally this update fixes a regression with DLA-4053-1 affecting
    drive sharing.

    CVE-2022-24882

      FreeRDP is a free implementation of the Remote Desktop Protocol
      (RDP). In versions prior to 2.7.0, NT LAN Manager (NTLM)
      authentication does not properly abort when someone provides and
      empty password value. This issue affects
      FreeRDP based RDP Server implementations. RDP clients are not
      affected.

    CVE-2022-39320

      FreeRDP is a free remote desktop protocol library and clients.
      Affected versions of FreeRDP may attempt integer addition on too
      narrow types leads to allocation of a buffer too small holding the
      data written. A malicious server can trick a FreeRDP based client to
      read out of bound data and send it back to the server. This issue
      has been addressed in version 2.9.0 and all users are advised to
      upgrade. Users unable to upgrade should not use the `/usb`
      redirection switch.

    For Debian 11 bullseye, these problems have been fixed in version
    2.3.0+dfsg1-2+deb11u3.

    We recommend that you upgrade your freerdp2 packages.
