| Detailed Description |
The remote system does not apply RHSA-2019:2473 which is kernel security update. The system which does not apply the update is affected by the following vulnerabilities:
- page cache side channel attacks (CVE-2019-5489)
- Salsa20 encryption algorithm does not correctly handle zero-length inputs allowing local attackers to cause denial-of-service (CVE-2017-17805)
- Unprivileged users able to inspect kernel stacks of arbitrary tasks (CVE-2018-17972)
- Spectre SWAPGS gadget vulnerability (CVE-2019-1125)
Note: This check solely relied on the kernel RPM version of the remote system to assess this vulnerability, so this might be a false positive.
