Huawei EulerOS: Security Advisory for keepalived (EulerOS-SA-2020-1357)

The remote host is missing an update for the Huawei EulerOS 'keepalived' package(s) announced via the EulerOS-SA-2020-1357 advisory.

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 2.0.8 didn't check for existing plain files when writing data to a temporary file upon a call to PrintData or PrintStats. If a local attacker had previously created a file with the expected name (e.g., /tmp/keepalived.data or /tmp/keepalived.stats), with read access for the attacker and write access for the keepalived process, then this potentially leaked sensitive information.(CVE-2018-19046)
