FreeRDP 3.11.0 through 3.30.0 Heap Buffer Overflow via Monitor Index
CVSS Score
6.6
EPSS Score
0.0%
EPSS Percentile
0th
FreeRDP versions before 3.31.0 fail to validate MonitorIds array values when parsing RDP connection files, allowing unbounded array indexing in xf_detect_monitors. Attackers can craft a malicious RDP file with an out-of-range selectedmonitors value to trigger out-of-bounds heap read and write operations when opened in xfreerdp.
