EulerOS 2.0 SP3 : freerdp (EulerOS-SA-2021-1785)

medium Nessus Plugin ID 149177

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the freerdp packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

- libfreerdp/core/update.c in FreeRDP versions > 1.1 through 2.0.0-rc4 has an Out-of-bounds Read.(CVE-2020-11526)

- In FreeRDP greater than 1.1 and before 2.0.0, there is an out-of-bounds read in update_read_icon_info. It allows reading a attacker-defined amount of client memory (32bit unsigned -> 4GB) to an intermediate buffer. This can be used to crash the client or store information for later retrieval. This has been patched in 2.0.0.(CVE-2020-11042)

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.

Solution

Update the affected freerdp packages.
