According to the version of the keepalived package installed, the EulerOS installation on the remote host is affected by the following vulnerability :

  - keepalived 2.0.8 didn't check for pathnames with     symlinks when writing data to a temporary file upon a     call to PrintData or PrintStats. This allowed local     users to overwrite arbitrary files if     fs.protected_symlinks is set to 0, as demonstrated by a     symlink from /tmp/keepalived.data or     /tmp/keepalived.stats to /etc/passwd.(CVE-2018-19044)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Security Fix(es) :

  - keepalived: Improper pathname validation allows for     overwrite of arbitrary filenames via symlinks     (CVE-2018-19044)

Security fix for CVE-2018-19044, CVE-2018-19045, CVE-2018-19046, CVE-2018-19115

Security issues fixed (bsc#1015141) :

  - CVE-2018-19045: Fixed mode when creating new temporary     files upon a call to PrintData or PrintStats

  - CVE-2018-19046: Fixed a check for existing plain files     when writing data to a temporary file upon a call to     PrintData or PrintStats

Non-security issues fixed :

  - Replace references to /var/adm/fillup-templates with new     %_fillupdir macro (boo#1069468)

According to the versions of the keepalived package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - keepalived 2.0.8 didn't check for pathnames with     symlinks when writing data to a temporary file upon a     call to PrintData or PrintStats. This allowed local     users to overwrite arbitrary files if     fs.protected_symlinks is set to 0, as demonstrated by a     symlink from /tmp/keepalived.data or     /tmp/keepalived.stats to /etc/passwd.(CVE-2018-19044)

  - keepalived before 2.0.7 has a heap-based buffer     overflow when parsing HTTP status codes resulting in     DoS or possibly unspecified other impact, because     extract_status_code in lib/html.c has no validation of     the status code and instead writes an unlimited amount     of data to the heap.(CVE-2018-19115)
