Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
EUVDB-ID: #VU14173
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-2018-0498
CWE-ID:
CWE-200 - Information exposure
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to obtain potentially sensitive information.
The vulnerability exists in ARM mbed TLS due to insufficient security restrictions imposed by the affected software when a cipher suite based on cipher block chaining (CBC) is used. A remote attacker who is able to observe and manipulate network packets can conduct a timing-based side-channel attack and partially recover the plaintext content.
MitigationUpdate to version 2.12.0, 2.7.5 or 2.1.14.
Vulnerable software versionsmbed TLS: 1.3.0 - 2.8.0

CVE-ID: CVE-2018-0497
CWE-ID:
CWE-200 - Information exposure
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to obtain potentially sensitive information.
The vulnerability exists in ARM mbed TLS due to incomplete fix for CVE-2013-0169 and improper calculation of the secure hash algorithm-384 (SHA-384) when using a cipher suite based on cipher block chaining (CBC). A remote attacker who is able to observe and manipulate network packets can conduct a timing-based side-channel attack and partially recover the plaintext content.
MitigationUpdate to version 2.12.0, 2.7.5 or 2.1.14.
