OpenPKG Security Advisory The OpenPKG Project

OpenPKG-SA-2004.001 08-Jan-2004
________________________________________________________________________
Package: inn
Vulnerability: remote code execution
OpenPKG Specific: no
Affected Releases: Affected Packages: Corrected Packages:
OpenPKG CURRENT <= inn-2.4.0-20031111 >= inn-2.4.0-20040108
OpenPKG 1.3 <= inn-2.4.0-1.3.0 >= inn-2.4.0-1.3.1
OpenPKG 1.2 none N.A.
Description:
According to INN [0] announcement postings from Russ Allbery [1][2],
Dan Riley discovered a buffer overflow in a portion of the control
message handling code, first introduced in INN 2.4.0. It is fairly
likely that this overflow is remotely exploitable to gain access and
execute code under the user innd(8) runs as. INN 2.3.x and earlier
versions are not affected.
Please check whether you are affected by running "/bin/rpm
-q inn". If you have the "inn" package installed and its version
is affected (see above), we recommend that you immediately upgrade
it (see Solution). [3][4]
Solution:
Select the updated source RPM appropriate for your OpenPKG release
[5], fetch it from the OpenPKG FTP service [6] or a mirror location,
verify its integrity [7], build a corresponding binary RPM from it [3]
and update your OpenPKG installation by applying the binary RPM [4].
For the current release OpenPKG 1.3, perform the following operations
to permanently fix the security problem (for other releases adjust
accordingly).
$ ftp ftp.openpkg.org
ftp> bin
ftp> cd release/1.3/UPD
ftp> get inn-2.4.0-1.3.1.src.rpm
ftp> bye
$ /bin/rpm -v --checksig inn-2.4.0-1.3.1.src.rpm
$ /bin/rpm --rebuild inn-2.4.0-1.3.1.src.rpm
$ su -
# /bin/rpm -Fvh /RPM/PKG/inn-2.4.0-1.3.1.*.rpm
