Frequently Asked Questions
Which systems are in scope for this update?
Systems with Rocky Linux FreeRDP packages installed are in scope, including freerdp, freerdp-libs, freerdp-devel, libwinpr, and their debuginfo/debugsource packages. The xfreerdp client is specifically described as connecting to RDP servers.
What does the advisory indicate about exploit prerequisites?
The supplied severity vector indicates network access is the attack vector, no privileges are required, and no user interaction is required. It also rates attack complexity as high.
What types of failures are addressed?
The update addresses three denial-of-service issues: uninitialized progressive tile handling, a heap-based buffer overflow during MP3 audio decoding, and a heap out-of-bounds write in NTLM authentication.
How can I determine whether a system needs attention?
Check whether any of the listed Rocky Linux FreeRDP or libwinpr packages are installed. The provided advisory data does not include fixed package versions, so it cannot be used alone to determine whether a particular installed version contains the fixes.
