CVE-2008-2711 2 Fetchmail, Redhat 2 Fetchmail, Enterprise Linux 2025-04-09 N/A
fetchmail 6.3.8 and earlier, when running in -v -v (aka verbose) mode, allows remote attackers to cause a denial of service (crash and persistent mail failure) via a malformed mail message with long headers, which triggers an erroneous dereference when using vsnprintf to format log messages.
CVE-2006-5867 2 Fetchmail, Redhat 2 Fetchmail, Enterprise Linux 2025-04-09 N/A
fetchmail before 6.3.6-rc4 does not properly enforce TLS and may transmit cleartext passwords over unsecured links if certain circumstances occur, which allows remote attackers to obtain sensitive information via man-in-the-middle (MITM) attacks.
CVE-2007-4565 2 Fetchmail, Redhat 2 Fetchmail, Enterprise Linux 2025-04-09 N/A
sink.c in fetchmail before 6.3.9 allows context-dependent attackers to cause a denial of service (NULL dereference and application crash) by refusing certain warning messages that are sent over SMTP.
CVE-2021-39272 3 Fedoraproject, Fetchmail, Redhat 3 Fedora, Fetchmail, Enterprise Linux 2024-11-21 5.9 Medium
Fetchmail before 6.4.22 fails to enforce STARTTLS session encryption in some circumstances, such as a certain situation with IMAP and PREAUTH.
CVE-2021-36386 3 Fedoraproject, Fetchmail, Redhat 3 Fedora, Fetchmail, Enterprise Linux 2024-11-21 7.5 High
report_vbuild in report.c in Fetchmail before 6.4.20 sometimes omits initialization of the vsnprintf va_list argument, which might allow mail servers to cause a denial of service or possibly have unspecified other impact via long error messages. NOTE: it is unclear whether use of Fetchmail on any realistic platform results in an impact beyond an inconvenience to the client user.
