-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ________________________________________________________________________ OpenPKG Security Advisory The OpenPKG Project http://www.openpkg.org/security.html http://www.openpkg.org openpkg-securityat_private openpkgat_private OpenPKG-SA-2003.033 10-Jul-2003 ________________________________________________________________________ Package: infozip Vulnerability: overwrite arbitrary files OpenPKG Specific: no Affected Releases: Affected Packages: Corrected Packages: OpenPKG CURRENT <= infozip-20030306-20030708 >= infozip-20030710-20030710 OpenPKG 1.2 <= infozip-1.2.0-1.2.0 >= infozip-1.2.0-1.2.1 OpenPKG 1.1 <= infozip-1.1.0-1.1.0 >= infozip-1.1.0-1.1.1 Dependent Packages: none Description: A directory traversal vulnerability in UnZip 5.50 allows attackers to overwrite arbitrary files via invalid characters between two "." (dot) characters, which are filtered and result in a ".." sequence. The corrected packages include a patch taken from RedHat [1] ensuring that non-printable characters do not make it possible for a malicious .zip file to write to parent directories unless the "-:" command line parameter is specified. The Common Vulnerabilities and Exposures (CVE) project assigned the id CAN-2003-0282 [2] to the problem. Please check whether you are affected by running "<prefix>/bin/rpm -q infozip". If you have the "infozip" 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 1.2, perform the following operations to permanently fix the security problem (for other releases adjust accordingly). $ ftp ftp.openpkg.org ftp> bin ftp> cd release/1.2/UPD ftp> get infozip-1.2.0-1.2.1.src.rpm ftp> bye $ <prefix>/bin/rpm -v --checksig infozip-1.2.0-1.2.1.src.rpm $ <prefix>/bin/rpm --rebuild infozip-1.2.0-1.2.1.src.rpm $ su - # <prefix>/bin/rpm -Fvh <prefix>/RPM/PKG/infozip-1.2.0-1.2.1.*.rpm ________________________________________________________________________ References: [1] http://rhn.redhat.com/errata/RHSA-2003-199.html [2] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-0282 [3] http://www.openpkg.org/tutorial.html#regular-source [4] http://www.openpkg.org/tutorial.html#regular-binary [5] ftp://ftp.openpkg.org/release/1.1/UPD/infozip-1.1.0-1.1.1.src.rpm [6] ftp://ftp.openpkg.org/release/1.2/UPD/infozip-1.2.0-1.2.1.src.rpm [7] ftp://ftp.openpkg.org/release/1.1/UPD/ [8] ftp://ftp.openpkg.org/release/1.2/UPD/ [9] http://www.openpkg.org/security.html#signature ________________________________________________________________________ For security reasons, this advisory was digitally signed with the OpenPGP public key "OpenPKG <openpkgat_private>" (ID 63C4CB9F) of the OpenPKG project which you can retrieve from http://pgp.openpkg.org and hkp://pgp.openpkg.org.
