Description

The remote Oracle Linux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the ELSA-2019-2125 advisory.

 - Simultaneous Multi-threading (SMT) in processors can enable local users to exploit software vulnerable to timing attacks via a side-channel timing attack on 'port contention'. (CVE-2018-5407)

 - Bounds checking in Tianocompress before November 7, 2017 may allow an authenticated user to potentially enable an escalation of privilege via local access. (CVE-2017-5731)

 - Stack overflow in corrupted bmp for EDK II may allow unprivileged user to potentially enable denial of service or elevation of privilege via local access. (CVE-2018-12181)
