Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Man-in-the-Middle attack
EUVDB-ID: #VU2950
Risk: Medium
CVSSv4.0: 9.1 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:A/U:Green]
CVE-ID: CVE-2014-0224
CWE-ID:
CWE-310 - Cryptographic Issues
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to decrypt encrypted connections.
The vulnerability exists due to an error in OpenSSL. A remote attacker with ability to intercept network traffic can decrypt SSL connection and gain access to sensitive data.
Update the affected packages
Ubuntu: 12.04 - 14.04
CPE2.3 External linkshttps://www.ubuntu.com/usn/usn-2232-3/
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?
No. We are not aware of malware exploiting this vulnerability. However, a fully functional exploit for this vulnerability is available.
2) Buffer overflow
EUVDB-ID: #VU11533
Risk: High
CVSSv4.0: 9.2 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:A/U:Amber]
CVE-ID: CVE-2014-0195
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in OpenSSL when processing DTLS fragments to an OpenSSL DTLS client or server. A remote attacker can send a specially crafted request to vulnerable application and cause the server to crash or execute arbitrary code on the target system.
Successful exploitation of the vulnerability requires that server support DTLS.
