Arch Linux Security Advisory ASA-201503-6
Date : 2015-03-09
CVE-ID : CVE-2014-9116
Package : mutt
Type : denial of service
Remote : Yes
Link : https://wiki.archlinux.org/index.php/CVE
The package mutt before version 1.5.23-2 is vulnerable to denial of service.
Upgrade to 1.5.23-2.
# pacman -Syu "mutt>=1.5.23-2"
The problem has been fixed upstream but no release is available yet.
The write_one_header function 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.
A remote attacker is able to send mails with specially crafted headers
that leads to a crash resulting in denial of service.
