Summary

Moderate: fetchmail security update

Details

Fetchmail is a remote mail retrieval and forwarding utility intended for use over on-demand TCP/IP links, like SLIP or PPP connections. Fetchmail supports every remote-mail protocol currently in use on the Internet (POP2, POP3, RPOP, APOP, KPOP, all IMAPs, ESMTP ETRN, IPv6, and IPSEC) for retrieval. Then Fetchmail forwards the mail through SMTP so the user can read it through their favorite mail client.

Security Fix(es):

fetchmail: DoS or information disclosure when logging long messages (CVE-2021-36386)
fetchmail: STARTTLS session encryption bypassing (CVE-2021-39272)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

CVE-2021-36386 (GCVE-0-2021-36386)

Vulnerability from cvelistv5 – Published: 2021-07-29 13:59 – Updated: 2024-08-04 00:54

Summary

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.

Severity ?

No CVSS data available.
