Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Man-in-the-middle attack

EUVDB-ID: #VU86

Risk: Medium

CVSSv4.0: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:A/U:Green]

CVE-ID: CVE-2015-4000

CWE-ID: CWE-300 - Channel Accessible by Non-Endpoint ('Man-in-the-Middle')

Exploit availability: Yes

Description

The vulnerability allows a remote attacker to decrypt TLS connections in certain situations.

The vulnerability exists due to boundary error when parsing HTTP requests. A remote unauthenticated attacker can conduct a man-in-the-middle attack that can lead to the target system to downgrade the Diffie-Hellman algorithm to 512-bit export-grade cryptography.

Successful exploitation of this vulnerability may result in modification of authentication information

Mitigation

Update the affected package java-1_8_0-openjdk to the latest version.
