-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ________________________________________________________________________ OpenPKG Security Advisory The OpenPKG Project http://www.openpkg.org/security.html http://www.openpkg.org openpkg-security@xxxxxxxxxxx openpkg@xxxxxxxxxxx OpenPKG-SA-2004.042 15-Sep-2004 ________________________________________________________________________ Package: aspell Vulnerability: arbitrary code execution OpenPKG Specific: no Affected Releases: Affected Packages: Corrected Packages: OpenPKG CURRENT <= aspell-0.50.5-20040310 >= aspell-0.60-20040827 OpenPKG 2.1 <= aspell-0.50.5-2.1.0 >= aspell-0.50.5-2.1.1 OpenPKG 2.0 <= aspell-0.50.5-2.0.0 >= aspell-0.50.5-2.0.1 Dependent Packages: none Description: According to a security advisory from shaun2k2 [0], multiple stack-based buffer overflows exists in the "word-list-compress" utility from the spell-checker GNU Aspell [1]. By providing a specially crafted word list containing an overly long string (more than 256 bytes), an attacker can cause a buffer overflow and execute arbitrary code. This allows an attacker to execute arbitrary code via a long entry in the wordlist. The Common Vulnerabilities and Exposures (CVE) project assigned the id CAN-2004-0548 [2] to the problem. Please check whether you are affected by running "<prefix>/bin/openpkg rpm -q aspell". If you have the "aspell" package installed and its version is affected (see above), we recommend that you immediately upgrade it (see Solution) and its dependent packages (see above), if any, too [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 2.1, perform the following operations to permanently fix the security problem (for other releases adjust accordingly). $ ftp ftp.openpkg.org ftp> bin ftp> cd release/2.1/UPD ftp> get aspell-0.50.5-2.1.1.src.rpm ftp> bye $ <prefix>/bin/openpkg rpm -v --checksig aspell-0.50.5-2.1.1.src.rpm $ <prefix>/bin/openpkg rpm --rebuild aspell-0.50.5-2.1.1.src.rpm $ su - # <prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/aspell-0.50.5-2.1.1.*.rpm ________________________________________________________________________ References: [0] http://marc.theaimsgroup.com/?l=bugtraq&m=108675120224531&w=2 [1] http://aspell.net/ [2] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0548 [3] http://www.openpkg.org/tutorial.html#regular-source [4] http://www.openpkg.org/tutorial.html#regular-binary [5] ftp://ftp.openpkg.org/release/2.1/UPD/aspell-0.50.5-2.1.1.src.rpm [6] ftp://ftp.openpkg.org/release/2.0/UPD/aspell-0.50.5-2.0.1.src.rpm [7] ftp://ftp.openpkg.org/release/2.1/UPD/ [8] ftp://ftp.openpkg.org/release/2.0/UPD/ [9] http://www.openpkg.org/security.html#signature ________________________________________________________________________ For security reasons, this advisory was digitally signed with the OpenPGP public key "OpenPKG <openpkg@xxxxxxxxxxx>" (ID 63C4CB9F) of the OpenPKG project which you can retrieve from http://pgp.openpkg.org and hkp://pgp.openpkg.org.
