Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Observable discrepancy

EUVDB-ID: #VU82583

Risk: Medium

CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2023-33850

CWE-ID: CWE-203 - Observable discrepancy

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to timing-based side channel in the RSA Decryption implementation. A remote attacker can send an overly large number of trial messages for decryption and gain unauthorized access to sensitive information on the system.

Mitigation

Install update from vendor's website.

Vulnerable software versions
