Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Improper input validation
EUVDB-ID: #VU13325
Risk: Low
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-0732
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to improper handling of large prime values by the affected software during key agreement operations in a Transport Layer Security (TLS) handshake using an Ephemeral Diffie-Hellman (DHE) based cipher suite. A remote attacker can send a large prime value from a malicious OpenSSL server to a targeted OpenSSL client and cause the client to stop responding while generating a key for the prime value.
MitigationUpdate the affected packages.
Opensuse: 42.3

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.
2) Information disclosure
EUVDB-ID: #VU11854
Risk: Low
CVSSv3.1: 2.9 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-0737
CWE-ID:
CWE-200 - Information exposure
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to obtain potentially sensitive information on the target system.
The weakness exists in the RSA key generation algorithm's BN_mod_inverse() and BN_mod_exp_mont() functions due to a cache timing side channel attack. A local attacker can recover the private key.
Update the affected packages.

Q & 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.
3) Resource exhaustion
EUVDB-ID: #VU11294
Risk: Low
CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-0739
CWE-ID:
CWE-400 - Resource exhaustion
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists due to excessive stack memory consumption. A remote attacker can cause the service to crash.
Update the affected packages.
