According to the versions of the freerdp packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :
In FreeRDP before version 2.1.2, there is an out-of-bound read in glyph_cache_put. This affects all FreeRDP clients with +glyph-cache
option enabled This is fixed in version 2.1.2.(CVE-2020-11098)
In FreeRDP before version 2.1.2, there is an out of bounds read in RLEDECOMPRESS. All FreeRDP based clients with sessions with color depth < 32 are affected. This is fixed in version 2.1.2.(CVE-2020-4033)
In FreeRDP before 2.1.0, there is an out-of-bound read in irp functions (parallel_process_irp_create, serial_process_irp_create, drive_process_irp_write, printer_process_irp_write, rdpei_recv_pdu, serial_process_irp_write). This has been fixed in 2.1.0.(CVE-2020-11089)
An issue was discovered in FreeRDP before 2.1.1. An out-of-bounds (OOB) write vulnerability has been detected in crypto_rsa_common in libfreerdp/crypto/crypto.c.(CVE-2020-13398)
Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
