-----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-2005.001 11-Jan-2005 ________________________________________________________________________ Package: perl Vulnerability: information disclosure, insecure permissions OpenPKG Specific: no Affected Releases: Affected Packages: Corrected Packages: OpenPKG CURRENT <= perl-5.8.6-20041129 >= perl-5.8.6-20050111 OpenPKG 2.2 <= perl-5.8.5-2.2.0 >= perl-5.8.5-2.2.1 OpenPKG 2.1 <= perl-5.8.4-2.1.0 >= perl-5.8.4-2.1.1 Dependent Packages: none Description: Jeroen van Wolffelaar discovered that the rmtree() function in the Perl [0] File::Path module removes directory trees in an insecure manner which could lead to the removal of arbitrary files and directories through a symlink attack. The Common Vulnerabilities and Exposures (CVE) project assigned the id CAN-2004-0452 [1] to the problem. Trustix developers discovered several insecure uses of temporary files in many modules which allow a local attacker to overwrite files via a symlink attack. The Common Vulnerabilities and Exposures (CVE) project assigned the id CAN-2004-0976 [2] to the problem. Please check whether you are affected by running "<prefix>/bin/openpkg rpm -q perl". If you have the "perl" 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 2.2, perform the following operations to permanently fix the security problem (for other releases adjust accordingly). $ ftp ftp.openpkg.org ftp> bin ftp> cd release/2.2/UPD ftp> get perl-5.8.5-2.2.1.src.rpm ftp> bye $ <prefix>/bin/openpkg rpm -v --checksig perl-5.8.5-2.2.1.src.rpm $ <prefix>/bin/openpkg rpm --rebuild perl-5.8.5-2.2.1.src.rpm $ su - # <prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/perl-5.8.5-2.2.1.*.rpm ________________________________________________________________________ References: [0] http://www.perl.com/ [1] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0452 [2] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0976 [3] http://www.openpkg.org/tutorial.html#regular-source [4] http://www.openpkg.org/tutorial.html#regular-binary [5] ftp://ftp.openpkg.org/release/2.2/UPD/perl-5.8.5-2.2.1.src.rpm [6] ftp://ftp.openpkg.org/release/2.1/UPD/perl-5.8.4-2.1.1.src.rpm [7] ftp://ftp.openpkg.org/release/2.2/UPD/ [8] ftp://ftp.openpkg.org/release/2.1/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.
