EUVDB-ID: #VU25109

Risk: High

CVSSv3.1: 7.1 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2020-7059

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to potentially sensitive information or perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary condition when using the "fgetss()" function to read data with stripping tags. A remote attacker can supply data that will cause this function to read past the allocated buffer, trigger out-of-bounds read error and read contents of memory on the system or crash the application.
