CVE-2008-3889
Status: ModifiedLow (2.1)—
Postfix 2.4 before 2.4.9, 2.5 before 2.5.5, and 2.6 before 2.6-20080902, when used with the Linux 2.6 kernel, leaks epoll file descriptors during execution of "non-Postfix" commands, which allows local users to cause a denial of service (application slowdown or exit) via a crafted command, as demonstrated by a command in a .forward file.
CVSS
- Version: 2.0
- Vector: AV:L/AC:L/Au:N/C:N/I:N/A:P
- Base score: 2.1
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 0.70%
- Percentile among all scored CVEs: 52
- Score date: 10/5/2026
EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
