CVE-2014-9116

Publication date 2 December 2014

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

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.
