Status: ModifiedMedium (5)—
lib-mail/message-header-parser.c in Dovecot 1.2.x before 1.2.17 and 2.0.x before 2.0.13 does not properly handle '\0' characters in header names, which allows remote attackers to cause a denial of service (daemon crash or mailbox corruption) via a crafted e-mail message.
CVSS
- Version: 2.0
- Vector: AV:N/AC:L/Au:N/C:N/I:N/A:P
- Base score: 5
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 3.25%
- Percentile among all scored CVEs: 88
- Score date: 10/7/2026
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).
