Frequently Asked Questions
Which FreeRDP functionality is implicated by the listed fixes?
The fixes cover progressive tile handling, MP3 audio decoding, and NTLM authentication. The identified outcomes are denial of service, including issues involving a heap-based buffer overflow and a heap out-of-bounds write.
Could an unauthenticated network attacker exploit these issues?
The supplied CVSS vector lists network attack vector and no privileges or user interaction requirements, but high attack complexity. The advisory data does not provide further exploitation prerequisites for the individual flaws.
What is the reported impact on confidentiality, integrity, and availability?
The provided CVSS vector reports no confidentiality impact and high integrity and availability impact. The description specifically identifies denial-of-service issues for all three listed CVEs.
