Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Information disclosure

EUVDB-ID: #VU5373

Risk: Critical

CVSSv4.0: 9.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:A/U:Red]

CVE-ID: CVE-2014-0160

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

Exploit availability: Yes

Description

The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.

The weakness exists due to an error in the TLS/DTLS heartbeat functionality. A remote attacker can read system memory contents without needing to log on to the server and retrieve private keys, passwords or other sensitive information

Successful exploitation of the vulnerability results in information disclosure on the vulnerable system.

Note: the vulnerability was being actively exploited.


Mitigation

Update the affected packages.
dev-libs/openssl to version: 1.0.1g

Vulnerable software versions

Gentoo Linux: All versions

dev-libs/openssl: All versions

Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.

Is there known malware, which exploits this vulnerability?

Yes. This vulnerability is being exploited in the wild.

2) Cryptographic issues

EUVDB-ID: #VU77192

Risk: Low

CVSSv4.0: 0.5 [CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2014-0076

CWE-ID: CWE-310 - Cryptographic Issues

Exploit availability: No

Description

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

The vulnerability exists due to montgomery ladder implementation in OpenSSL does not ensure that certain swap operations have a constant-time behavior. A local attacker can obtain ECDSA nonces via a FLUSH+RELOAD cache side-channel attack.

Mitigation

Update the affected packages.
dev-libs/openssl to version: 1.0.1g

Vulnerable software versions

Gentoo Linux: All versions

dev-libs/openssl: All versions
