CVE-2023-42822 is an out-of-bounds read vulnerability in xrdp, an open-source remote desktop protocol server, affecting fedoraproject and neutrinolabs xrdp versions. The vulnerability stems from a lack of bounds checking when accessing font glyphs, allowing a malicious user to trigger an out-of-bounds read within a potentially privileged process, especially on non-Debian systems where xrdp often runs as root. With a CVSS score of 6.5 (Medium), it can be exploited remotely with low attack complexity and no user interaction, potentially leading to high confidentiality impact. There is currently no evidence of active exploitation, public exploit code, or significant community discussion, and it is not listed in CISA's KEV catalog.
