AI-suggested
A patch is available and the issue is fixed in FreeRDP version 3.32.2 and later. Users should update to the fixed package versions provided by Ubuntu security notices (e.g., 3.32.2+dfsg-0ubuntu0.24.04.1, 3.32.2+dfsg-0ubuntu0.26.10.1, 3.32.2+dfsg-0ubuntu0.26.04.1). Standard system updates will apply the necessary fixes.
Description
FreeRDP versions before 3.32.2 built with WITH_AAD=ON contain a reachable assertion vulnerability due to improper handling of the redirectedServerCert field in the ARM gateway response parser. This can cause the client process to abort when a malicious or malformed gateway returns a response with a missing or non-string redirectedServerCert field.
