Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Null pointer dereference
EUVDB-ID: #VU10322
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-2017-10790
CWE-ID:
CWE-476 - NULL Pointer Dereference
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists in the _asn1_check_identifier function in GNU Libtasn1 due to insufficient validation of user-supplied input. A remote attacker can submit a specially crafted input, trigger assignment of a NULL value within an asn1_node structure and cause the service to crash.
Update the affected packages.
Opensuse: 15.0

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) Use of a broken or risky cryptographic algorithm
EUVDB-ID: #VU15707
Risk: Low
CVSSv3.1: 3.5 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-10844
CWE-ID:
CWE-327 - Use of a Broken or Risky Cryptographic Algorithm
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to usage of an insecure implementation of HMAC-SHA-256 algorithm vulnerable to a Lucky thirteen style attack. A remote attacker with ability to intercept traffic can recover encrypted data.
MitigationUpdate the affected packages.

3) Use of a broken or risky cryptographic algorithm
EUVDB-ID: #VU15708
Risk: Low
CVSSv3.1: 3.5 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-10845
CWE-ID:
CWE-327 - Use of a Broken or Risky Cryptographic Algorithm
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to usage of an insecure implementation of HMAC-SHA-384 algorithm vulnerable to a Lucky thirteen style attack. A remote attacker with ability to intercept traffic can recover encrypted data.
MitigationUpdate the affected packages.

4) Cryptographic issues
EUVDB-ID: #VU15709
Risk: Low
CVSSv3.1: 3.5 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-10846
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 a cache-based side channel in GnuTLS implementation that can lead to recovery of data in cross-VM attack setting. A remote attacker with ability to intercept traffic can recover encrypted data using a combination of "Just in Time" Prime+probe attack in combination with Lucky-13 attack.
MitigationUpdate the affected packages.
