Package: uudeview
Vulnerability: insecure temp file handling, buffer overflow
OpenPKG Specific: no

Affected Releases: Affected Packages: Corrected Packages:
OpenPKG CURRENT <= uudeview-0.5.20-20040302 >= uudeview-0.5.20-20040312
OpenPKG 2.0 <= uudeview-0.5.19-2.0.0 >= uudeview-0.5.19-2.0.1
OpenPKG 1.3 <= uudeview-0.5.18-1.3.0 >= uudeview-0.5.18-1.3.1

Dependent Packages: none

Description:
Alerted by a posting on Bugtraq [1] the UUDeview [2] package was
reviewed. It was found that 0.5.19 and later contains a bug which
leads to failure retrieving the filename during decode. All versions
suffered from insecure temporary file handling. Version 0.5.20
contains bug fixes for the parsing of header lines, exact handling of
maximum line length and fixes for two buffer overflows which needed
backporting. The corected packages listed above remedy all of these
problems.

Please check whether you are affected by running "<prefix>/bin/rpm
-q uudeview". If you have the "uudeview" 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][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 most recent release OpenPKG 2.0, perform the
following operations to permanently fix the security problem (for
other releases adjust accordingly).

$ ftp ftp.openpkg.org
ftp> bin
ftp> cd release/2.0/UPD
ftp> get uudeview-0.5.19-2.0.1.src.rpm
ftp> bye
$ <prefix>/bin/openpkg rpm -v --checksig uudeview-0.5.19-2.0.1.src.rpm
$ <prefix>/bin/openpkg rpm --rebuild uudeview-0.5.19-2.0.1.src.rpm
$ su -
# <prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/uudeview-0.5.19-2.0.1.*.rpm
