OpenPKG Security Advisory The OpenPKG Project http://www.openpkg.org/security.html http://www.openpkg.org [e-mail:openpkg-security@openpkg.org] [e-mail:openpkg@openpkg.org] OpenPKG-SA-2004.006 12-Mar-2004 ________________________________________________________________________

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 "/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).
