| CVE | 摘要 | 来源 | 最高 CVSS | EPSS % | 公开时间 | 更新时间 |
|---|---|---|---|---|---|---|
| CVE-2021-44225 | In Keepalived through 2.2.4, the D-Bus policy does not sufficiently restrict the message destination, allowing any user to inspect and manipulate any property. This leads to access-control bypass in some situations in which an unrelated D-Bus system service has a settable (writable) property | [email protected] | 5.4 | 1.16% | 2021-11-25 | 2026-06-17 |
| CVE-2018-19115 | 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. | [email protected] | 9.8 | 3.67% | 2018-11-08 | 2026-06-16 |
| CVE-2018-19046 | 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. | [email protected] | 4.7 | 0.37% | 2018-11-08 | 2026-06-16 |
| CVE-2018-19045 | keepalived 2.0.8 used mode 0666 when creating new temporary files upon a call to PrintData or PrintStats, potentially leaking sensitive information. | [email protected] | 7.5 | 2.38% | 2018-11-08 | 2026-06-16 |
| CVE-2018-19044 | 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. | [email protected] | 4.7 | 0.50% | 2018-11-08 | 2026-06-16 |
| CVE-2011-1784 | The pidfile_write function in core/pidfile.c in keepalived 1.2.2 and earlier uses 0666 permissions for the (1) keepalived.pid, (2) checkers.pid, and (3) vrrp.pid files in /var/run/, which allows local users to kill arbitrary processes by writing a PID to one of these files. | [email protected] | 3.6 | 0.37% | 2011-05-20 | 2026-06-16 |
