Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Improper input validation
EUVDB-ID: #VU15917
Risk: Low
CVSSv3.1: 3 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L/E:P/RL:O/RC:C]
CVE-ID: CVE-2017-7519
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to cause DoS condition.
The vulnerability exists due to a format string error when the libradosstriper library parses user-supplied inpuе. A local attacker can submit malicious input and cause an application or service using the affected library to crash.
MitigationUpdate the affected package to version: 10.2.11-1
Vulnerable software versionsDebian Linux: All versions

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. However, proof of concept for this vulnerability is available.
2) Security restrictions bypass
EUVDB-ID: #VU14329
Risk: Low
CVSSv3.1: 4.8 [CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-10861
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows an adjacent authenticated attacker to bypass security restrictions on the target system.
The vulnerability exists in ceph branches master, mimic, luminous and jewel due to improper handling of user-supplied requests by ceph mon. An adjacent attacker with read access to ceph can delete, create ceph storage pools and corrupt snapshot images.
MitigationUpdate the affected package to version: 10.2.11-1
Vulnerable software versionsDebian Linux: All versions

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote authenticated user via the local network (LAN).
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
3) Security restrictions bypass
EUVDB-ID: #VU14542
Risk: Low
CVSSv3.1: 4.4 [CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-1128
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: No
DescriptionThe vulnerability allows an adjacent attacker to conduct replay attack on the target system.
The vulnerability exists in ceph branches master, mimic, luminous and jewel due to cephx authentication protocol did not verify ceph clients correctly. An adjacent attacker with access to ceph cluster network who is able to sniff packets on network can authenticate with ceph service, perform actions allowed by ceph service, conduct replay attack and bypass security restrictions.
MitigationUpdate the affected package to version: 10.2.11-1
Vulnerable software versionsDebian Linux: All versions
External linkshttp://www.debian.org/security/2018/dsa-4339
Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the local network (LAN).
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
4) Security restrictions bypass
EUVDB-ID: #VU14543
Risk: Low
CVSSv3.1: 4.4 [CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-1129
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: No
DescriptionThe vulnerability allows an adjacent attacker to bypass security restrictions on the target system.
The vulnerability exists in ceph branches master, mimic, luminous and jewel due to improper handling of signature calculation by cephx authentication protocol. An adjacent attacker with access to ceph cluster network who is able to alter the message payload can bypass signature checks done by cephx protocol to conduct further attacks.
MitigationUpdate the affected package to version: 10.2.11-1
