Beschreibung:	Summary: The remote host is missing an update for the 'keepalived' package(s) announced via the MGASA-2018-0494 advisory. Vulnerability Insight: keepalived before version 2.0.9 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 version 2.0.9 used mode 0666 when creating new temporary files upon a call to PrintData or PrintStats, potentially leaking sensitive information (CVE-2018-19045). keepalived before version 2.0.10 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). keepalived before version 2.0.9 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). Affected Software/OS: 'keepalived' package(s) on Mageia 6. Solution: Please install the updated package(s). CVSS Score: 7.5 CVSS Vector: AV:N/AC:L/Au:N/C:P/I:P/A:P
