The remote CentOS Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the CESA-2023:2851 advisory.

  - FreeRDP is a free remote desktop protocol library and clients. FreeRDP based clients on unix systems using     `/parallel` command line switch might read uninitialized data and send it to the server the client is     currently connected to. FreeRDP based server implementations are not affected. Please upgrade to 2.8.1     where this issue is patched. If unable to upgrade, do not use parallel port redirection (`/parallel`     command line switch) as a workaround. (CVE-2022-39282)

  - FreeRDP is a free remote desktop protocol library and clients. All FreeRDP based clients when using the     `/video` command line switch might read uninitialized data, decode it as audio/video and display the     result. FreeRDP based server implementations are not affected. This issue has been patched in version     2.8.1. If you cannot upgrade do not use the `/video` switch. (CVE-2022-39283)

  - FreeRDP is a free remote desktop protocol library and clients. In affected versions there is an out of     bound read in ZGFX decoder component of FreeRDP. A malicious server can trick a FreeRDP based client to     read out of bound data and try to decode it likely resulting in a crash. This issue has been addressed in     the 2.9.0 release. Users are advised to upgrade. (CVE-2022-39316)

  - FreeRDP is a free remote desktop protocol library and clients. Affected versions of FreeRDP are missing a     range check for input offset index in ZGFX decoder. A malicious server can trick a FreeRDP based client to     read out of bound data and try to decode it. This issue has been addressed in version 2.9.0. There are no     known workarounds for this issue. (CVE-2022-39317)

  - FreeRDP is a free remote desktop protocol library and clients. Affected versions of FreeRDP are missing     input validation in `urbdrc` channel. A malicious server can trick a FreeRDP based client to crash with     division by zero. This issue has been addressed in version 2.9.0. All users are advised to upgrade. Users     unable to upgrade should not use the `/usb` redirection switch. (CVE-2022-39318)

  - FreeRDP is a free remote desktop protocol library and clients. Affected versions of FreeRDP are missing     input length validation in the `urbdrc` channel. 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.
    (CVE-2022-39319)

  - 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. (CVE-2022-39320)

  - FreeRDP is a free remote desktop protocol library and clients. Affected versions of FreeRDP are missing     path canonicalization and base path check for `drive` channel. A malicious server can trick a FreeRDP     based client to read files outside the shared directory. 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 `/drive`, `/drives` or     `+home-drive` redirection switch. (CVE-2022-39347)

  - FreeRDP is a free remote desktop protocol library and clients. Affected versions of FreeRDP are missing     input length validation in `drive` channel. 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 drive redirection channel -     command line options `/drive`, `+drives` or `+home-drive`. (CVE-2022-41877)
