Last modified Jun 17, 2026

CVE-2020-11058 is a low-severity vulnerability rated 2.2/10 on the CVSS scale. In FreeRDP after 1.1 and before 2.0.0, a stream out-of-bounds seek in rdp_read_font_capability_set could lead to a later out-of-bounds read. As a result, a manipulated client or server might force a disconnect due to an invalid data read. EPSS estimates a 1.61% chance of exploitation in the next 30 days.
