CVE-2020-11058
Description
From CVE.org
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. This has been fixed in 2.0.0.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Red Hat CVSS v3 Score Explanation
AC:H because attacker would need control over data sent from RDP server to client. PR:H Because this needs to be sent by the server to which the victim client is connected to. Attacker would need control over server or social engineering. A:L Because this is not a persistent attack on the client. C:N because it has not been demonstrated that the out-of-bounds read can leak information to the attacker.
