Package: mutt
Vulnerability: buffer overflow in IMAP client
OpenPKG Specific: no

Affected Releases: Affected Packages: Corrected Packages:
OpenPKG CURRENT <= mutt-1.4i-20030103 >= mutt-1.4.1i-20030320
OpenPKG 1.2 <= mutt-1.4i-1.2.0 >= mutt-1.4i-1.2.1

According to a posting on Bugtraq [0], Edmund Grimley Evans fixed a
buffer overflow which exists in the IMAP client code of the mail user
agent Mutt [1]. The bug was found by Core Security Technologies [2].

Please check whether you are affected by running "/bin/rpm -q
mutt". If you have the "mutt" package installed and its version is
affected (see above), we recommend that you immediately upgrade it
(see Solution). [3][4]

Select the updated source RPM appropriate for your OpenPKG release
[5][6], fetch it from the OpenPKG FTP service [7][8] or a mirror
location, verify its integrity [9], build a corresponding binary RPM
from it [3] and update your OpenPKG installation by applying the binary
RPM [4]. For the current release OpenPKG 1.2, perform the following
operations to permanently fix the security problem (for other releases
adjust accordingly).

$ ftp
ftp> bin
ftp> cd release/1.2/UPD
ftp> get mutt-1.4i-1.2.1.src.rpm
ftp> bye
$ /bin/rpm -v --checksig mutt-1.4i-1.2.1.src.rpm
$ /bin/rpm --rebuild mutt-1.4i-1.2.1.src.rpm
$ su -
# /bin/rpm -Fvh /RPM/PKG/mutt-1.4i-1.2.1.*.rpm
