OpenPKG Security Advisory The OpenPKG Project http://www.openpkg.org/security.html http://www.openpkg.org [EMAIL PROTECTED] [EMAIL PROTECTED] OpenPKG-SA-2004.011 07-Apr-2004 ________________________________________________________________________ Package: sharutils Vulnerability: arbitrary code execution OpenPKG Specific: no Affected Releases: Affected Packages: Corrected Packages: OpenPKG CURRENT <= sharutils-4.2.1-20011201 >= sharutils-4.2.1-20040407 OpenPKG 2.0 <= sharutils-4.2.1-2.0.0 >= sharutils-4.2.1-2.0.1 OpenPKG 1.3 <= sharutils-4.2.1-1.3.0 >= sharutils-4.2.1-1.3.1 Dependent Packages: none Description: According to a posting on Bugtraq [1], Shaun Colley discovered and researched a stack-based buffer overflow vulnerability which exists in the GNU Sharutils [2] due to lack of bounds checking when handling the '-o' command-line option. Please check whether you are affected by running "<prefix>/bin/rpm -q sharutils". If you have the "sharutils" 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 sharutils-4.2.1-2.0.1.src.rpm ftp> bye $ <prefix>/bin/openpkg rpm -v --checksig sharutils-4.2.1-2.0.1.src.rpm $ <prefix>/bin/openpkg rpm --rebuild sharutils-4.2.1-2.0.1.src.rpm $ su - # <prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/sharutils-4.2.1-2.0.1.*.rpm ________________________________________________________________________ References: [1] http://www.securityfocus.com/archive/1/359639 [2] http://www.gnu.org/software/sharutils/ [3] http://www.openpkg.org/tutorial.html#regular-source [4] http://www.openpkg.org/tutorial.html#regular-binary [5] ftp://ftp.openpkg.org/release/1.3/UPD/sharutils-4.2.1-1.3.1.src.rpm [6] ftp://ftp.openpkg.org/release/2.0/UPD/sharutils-4.2.1-2.0.1.src.rpm [7] ftp://ftp.openpkg.org/release/1.3/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 <[EMAIL PROTECTED]>" (ID 63C4CB9F) of the OpenPKG project which you can retrieve from http://pgp.openpkg.org and hkp://pgp.openpkg.org.
