Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Cryptographic issues
EUVDB-ID: #VU21043
Risk: Low
CVSSv3.1: 3.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2019-1547
CWE-ID:
CWE-310 - Cryptographic Issues
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to decrypt traffic.
The vulnerability exists due to insufficient enforcement of side channel resistant code paths. A remote attacker with ability to create a large number of signatures, where explicit parameters with no co-factor is present, can force the application to fall back to non-side channel resistant code pathsduring ECDSA signature operation and perform full key recovery.
Successful exploitation of the vulnerability may allow an attacker to decrypt communication between server and client.
MitigationInstall update from vendor's website.
Vulnerable software versionsEMC Data Domain: before 7.0.0.20
External linksQ & 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.
2) Cryptographic issues
EUVDB-ID: #VU23451
Risk: Low
CVSSv3.1: 3.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2019-1551
CWE-ID:
CWE-310 - Cryptographic Issues
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to an overflow issue within the rsaz_512_sqr(): the x64_64 Montgomery squaring procedure used in exponentiation with 512-bit moduli. A remote attacker can perform an attack against DH512 keys.

3) Padding oracle attack
EUVDB-ID: #VU21045
Risk: Low
CVSSv3.1: 3.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2019-1563
CWE-ID:
CWE-310 - Cryptographic Issues
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform padding oracle attack.
The vulnerability exists due to possibility to perform a Bleichenbacher padding oracle attack against the RSA key, in situations where an attacker receives automated notification of the success or failure of a decryption attempt an attacker. A remote attacker can send a very large number of messages to be decrypted, can recover a CMS/PKCS7 transported encryption key or decrypt any RSA encrypted message that was encrypted with the public RSA key.
MitigationInstall update from vendor's website.

No. We are not aware of malware exploiting this vulnerability.
4) Incorrect default permissions
EUVDB-ID: #VU19563
Risk: Low
CVSSv3.1: 3.9 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2019-1552
CWE-ID:
CWE-276 - Incorrect Default Permissions
Exploit availability: No
DescriptionThe vulnerability allows a local user to bypass security restrictions.
The vulnerability exists due to OpenSSL uses insecure by default directory with potentially insecure permissions for the OPENSSLDIR on Windows. A local user can modify OpenSSL's default configuration within the 'C:/usr/local' folder, insert CA certificates, modify (or even replace) existing engine modules and bypass security restrictions, based on OpenSSL security mechanisms.
Install update from vendor's website.
Vulnerable software versionsEMC Data Domain: before 7.0.0.20
External linksQ & A
Can this vulnerability be exploited remotely?
No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
