high Nessus Plugin ID 146158

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 :

 - In FreeRDP after 1.0 and before 2.0.0, there is an out-of-bound read in in update_read_bitmap_data that allows client memory to be read to an image buffer. The result displayed on screen as colour.(CVE-2020-11045)

 - libfreerdp/gdi/region.c in FreeRDP versions > 1.0 through 2.0.0-rc4 has an Integer Overflow.(CVE-2020-11523)

 - In FreeRDP before version 2.1.2, there is a global OOB read in update_read_cache_bitmap_v3_order. As a workaround, one can disable bitmap cache with
 -bitmap-cache (default). This is fixed in version 2.1.2.(CVE-2020-11096)

 - An exploitable code execution vulnerability exists in the authentication functionality of FreeRDP 2.0.0-beta1+android11. A specially crafted server response can cause an out-of-bounds write resulting in an exploitable condition. An attacker can compromise the server or use a man in the middle attack to trigger this vulnerability.(CVE-2017-2834)

 - An exploitable code execution vulnerability exists in the RDP receive functionality of FreeRDP 2.0.0-beta1+android11. A specially crafted server response can cause an out-of-bounds write resulting in an exploitable condition. An attacker can compromise the server or use a man in the middle to trigger this vulnerability.(CVE-2017-2835)

 - An exploitable denial of service vulnerability exists within the reading of proprietary server certificates in FreeRDP 2.0.0-beta1+android11. A specially crafted challenge packet can cause the program termination leading to a denial of service condition. An attacker can compromise the server or use man in the middle to trigger this vulnerability.(CVE-2017-2836)

 - An exploitable denial of service vulnerability exists within the handling of security data in FreeRDP 2.0.0-beta1+android11. A specially crafted challenge packet can cause the program termination leading to a denial of service condition. An attacker can compromise the server or use man in the middle to trigger this vulnerability.(CVE-2017-2837)

 - An exploitable denial of service vulnerability exists within the handling of challenge packets in FreeRDP 2.0.0-beta1+android11. A specially crafted challenge packet can cause the program termination leading to a denial of service condition. An attacker can compromise the server or use man in the middle to trigger this vulnerability.(CVE-2017-2838)

 - An exploitable denial of service vulnerability exists within the handling of challenge packets in FreeRDP 2.0.0-beta1+android11. A specially crafted challenge packet can cause the program termination leading to a denial of service condition. An attacker can compromise the server or use man in the middle to trigger this vulnerability.(CVE-2017-2839)
