Summary

CVE-2023-42801 is a buffer overflow vulnerability found in the Moonlight GameStream client code, specifically in the moonlight-common-c package. This vulnerability affects various products, including Qt, Android, iOS/tvOS, and Embedded. Exploiting the buffer overflow could potentially crash a Moonlight client, although achieving remote code execution (RCE) is unlikely due to stack canaries used by modern compiler toolchains. The bug was addressed in a commit that fixed the issue. To remediate this vulnerability, users should ensure they are using official clients with stack canaries and avoid pairing with malicious hosts. Although RCE is unlikely, organizations should still be cautious as a compromised Moonlight client could pose risks to confidentiality and availability.
