Security Bulletin
This security bulletin contains one high risk vulnerability.
EUVDB-ID: #VU47248
Risk: High
CVSSv3.1: 3.4 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2020-8252
CWE-ID:
CWE-120 - Buffer overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
The vulnerability exists due to incorrect validation of realpath in libuv. The library incorrectly determines the buffer size, which can result in a buffer overflow if the resolved path is longer than 256 bytes. A remote attacker can pass an overly long path to the application that is using the library, trigger memory corruption and execute arbitrary code on the system.
Install update from vendor's website.
Vulnerable software versionslibuv: 0.10.2 - 1.38.1
