Information disclosure in IBM Watson Speech Services Cartridge for IBM Cloud Pak for Data

1) Information disclosure

EUVDB-ID: #VU30596

Risk: Low

CVSSv3.1: 2.9 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-19126

CWE-ID: CWE-200 - Information exposure

Exploit availability: No

Description

The vulnerability allows a local authenticated user to gain access to sensitive information.

On the x86-64 architecture, the GNU C Library (aka glibc) before 2.31 fails to ignore the LD_PREFER_MAP_32BIT_EXEC environment variable during program execution after a security transition, allowing local attackers to restrict the possible mapping addresses for loaded libraries and thus bypass ASLR for a setuid program.

Mitigation

Install update from vendor's website.
