Summary

freerdp security update

Details

FreeRDP is a client implementation of the Remote Desktop Protocol (RDP) that follows Microsoft's open specifications. This package provides the client applications xfreerdp and wlfreerdp.

Security Fix(es):

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 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)

Severity

9.8 (Critical)
