Security Bulletin
This security bulletin contains information about 6 vulnerabilities.
1) Double free error
EUVDB-ID: #VU1622
Risk: Low
CVSSv3.1: 3.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2016-0705
CWE-ID:
CWE-415 - Double Free
Exploit availability: No
DescriptionThe vulnerability allows a remote unauthenticated attacker to cause DoS condition on the target system.
The weakness exists due to double-free error when parsing DSA private keys. A remote attacker can trigger memory corruption and cause the service to crash.
Install update from vendor's website.
Vulnerable software versionsIBM Algo One Core: 5.0.0 - 5.1.0
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) Information disclosure
EUVDB-ID: #VU5442
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-2017-3732
CWE-ID:
CWE-310 - Cryptographic Issues
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to propagating error in the x86_64 Montgomery squaring procedure. A remote attacker with access to unpatched vulnerable system that uses a shared private key with Diffie-Hellman (DH) parameters set can gain unauthorized access to sensitive private key information.
According to vendor’s advisory, this vulnerability is unlikely to be exploited in real-world attacks, as it requires significant resources and online access to an unpatched system using the target private key in a scenario with persistent DH parameters and a private key that is shared between multiple clients.
Vulnerability exploitation against RSA and DSA as a result of this defect would be very difficult to perform and are not believed likely.

3) Carry propagation issue
EUVDB-ID: #VU9109
Risk: Low
CVSSv3.1: 5.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2017-3736
CWE-ID:
CWE-310 - Cryptographic Issues
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to decrypt data.
The vulnerability exists due to carry propagating bug in the x86_64 Montgomery squaring procedure (bn_sqrx8x_internal). A remote attacker can decrypt encrypted data. The vulnerability affects processors that support the BMI1, BMI2 and ADX extensions like
Intel Broadwell (5th generation) and later or AMD Ryzen.

4) Use of a broken or risky cryptographic algorithm
EUVDB-ID: #VU12309
Risk: Low
CVSSv3.1: 5.4 [CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-1428
CWE-ID:
CWE-327 - Use of a Broken or Risky Cryptographic Algorithm
Exploit availability: No
DescriptionThe vulnerability allows a local unauthenticated attacker to obtain potentially sensitive information on the target system.
The weakness exists due to IBM GSKit uses weaker than expected cryptographic algorithms. A local attacker can gain access to potentially sensitive information.
Install update from vendor's website.
Vulnerable software versionsIBM Algo One Core: 5.0.0 - 5.1.0
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.
5) Integer overflow
EUVDB-ID: #VU12310
Risk: Low
CVSSv3.1: 5.4 [CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-1427
CWE-ID:
CWE-190 - Integer overflow
Exploit availability: No
DescriptionThe vulnerability allows a local unauthenticated attacker to cause DoS condition on the target system.
The weakness exists due to IBM GSKit contains several environment variables. A local attacker can cause the service to crash.

6) Use of cryptographically weak PRNG
EUVDB-ID: #VU12311
Risk: Low
CVSSv3.1: 6.4 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-1426
CWE-ID:
CWE-338 - Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG)
Exploit availability: No
DescriptionThe vulnerability allows a remote unauthenticated attacker to obtain potentially sensitive information and write arbitrary files on the target system.
The weakness exists due to IBM GSKit duplicates the PRNG state across fork() system calls when multiple ICC instances are loaded which can result in duplicate Session IDs and a risk of duplicate key material. A remote attacker can gain access to potentially sensitive information and write arbitrary files.
