    CVE-2014-9116

    Published: 2 Dec 2014Last Modified: 16 Apr 2026

    Summary:

    Details: The write_one_header function in mutt 1.5.23 does not properly handle newline characters at the beginning of a header, which allows remote attackers to cause a denial of service (crash) via a header with an empty body, which triggers a heap-based buffer overflow in the mutt_substrdup function.
