Alpine: multiple keepalived packages: security update to 2.0.7-r1 (deprecated)
high Tenable Cloud Security Plugin ID 400576
Description
There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:- 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 used mode 0666 when creating new temporary files upon a call to PrintData or PrintStats,
potentially leaking sensitive information. (CVE-2018-19045)
- 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)
