Message-ID: <[EMAIL PROTECTED]> From: OpenPKG <[EMAIL PROTECTED]> Sender: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Subject: [Full-Disclosure] [OpenPKG-SA-2003.050] OpenPKG Security Advisory (screen) Date: Fri, 28 Nov 2003 13:23:13 +0100 -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ________________________________________________________________________ OpenPKG Security Advisory The OpenPKG Project http://www.openpkg.org/security.html http://www.openpkg.org [EMAIL PROTECTED] [EMAIL PROTECTED] OpenPKG-SA-2003.050 28-Nov-2003 ________________________________________________________________________ Package: screen Vulnerability: privilege escalation OpenPKG Specific: no Affected Releases: Affected Packages: Corrected Packages: OpenPKG CURRENT <= screen-4.0.1-20031009 >= screen-4.0.1-20031127 OpenPKG 1.3 <= screen-3.9.15-1.3.0 >= screen-3.9.15-1.3.1 OpenPKG 1.2 <= screen-3.9.13-1.2.0 >= screen-3.9.13-1.2.1 Dependent Packages: none Description: Timo Sirainen reported and fixed [1] a buffer overflow bug which allows privilege escalation in the Virtual Screen Manager GNU screen [2], whose executable is installed setuid-root. It also has some potential for attackers getting control of another user's screen. Transfer of approximately two gigabytes of data is required to exploit this vulnerability. Please check whether you are affected by running "<prefix>/bin/rpm -q screen". If you have the "screen" 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 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 screen-3.9.15-1.3.1.src.rpm ftp> bye $ <prefix>/bin/rpm -v --checksig screen-3.9.15-1.3.1.src.rpm $ <prefix>/bin/rpm --rebuild screen-3.9.15-1.3.1.src.rpm $ su - # <prefix>/bin/rpm -Fvh <prefix>/RPM/PKG/screen-3.9.15-1.3.1.*.rpm ________________________________________________________________________ References: [1] http://www.securityfocus.com/archive/1/345844/2003-11-24/2003-11-30/0 [2] http://www.gnu.org/software/screen/ [3] http://www.openpkg.org/tutorial.html#regular-source [4] http://www.openpkg.org/tutorial.html#regular-binary [5] ftp://ftp.openpkg.org/release/1.2/UPD/screen-3.9.13-1.2.1.src.rpm [6] ftp://ftp.openpkg.org/release/1.3/UPD/screen-3.9.15-1.3.1.src.rpm [7] ftp://ftp.openpkg.org/release/1.2/UPD/ [8] ftp://ftp.openpkg.org/release/1.3/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.
