1) Out-of-bounds read

EUVDB-ID: #VU25110

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-2020-7060

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 certain "mbstring" functions to convert multibyte encodings. A remote attacker can supply data that will cause function "mbfl_filt_conv_big5_wchar" to read past the allocated buffer, trigger out-of-bounds read error and read contents of memory on the system or crash the application.

Mitigation

Install updates from vendor's repository.
