The problem allows a remote or local attacker to execute arbitrary code by causing a heap-based buffer overflow via quantifier values in regular expressions. As PCRE is a popular library, this problem affects many applications. The Common Vulnerabilities and Exposures (CVE) project assigned the id CAN-2005-2491 [2] to the problem. Please check whether you are affected by running "/bin/openpkg rpm -q pcre". If you have the "pcre" package installed and its version is affected (see above), we recommend that you immediately upgrade it (see Solution) and its dependent packages (see above), 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 2.4, perform the following operations to permanently fix the security problem (for other releases adjust accordingly). $ ftp ftp.openpkg.org ftp> bin ftp> cd release/2.4/UPD ftp> get pcre-6.0-2.4.1.src.rpm ftp> bye $ /bin/openpkg rpm -v --checksig pcre-6.0-2.4.1.src.rpm $ /bin/openpkg rpm --rebuild pcre-6.0-2.4.1.src.rpm $ su - # /bin/openpkg rpm -Fvh /RPM/PKG/pcre-6.0-2.4.1.*.rpm Additionally, we recommend that you rebuild and reinstall all dependent packages (see above), too [3][4]. ________________________________________________________________________ References: [1] http://www.pcre.org/ [2] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-2491 [3] http://www.openpkg.org/tutorial.html#regular-source [4] http://www.openpkg.org/tutorial.html#regular-binary [5] ftp://ftp.openpkg.org/release/2.4/UPD/pcre-6.0-2.4.1.src.rpm [6] ftp://ftp.openpkg.org/release/2.3/UPD/pcre-5.0-2.3.1.src.rpm [7] ftp://ftp.openpkg.org/release/2.4/UPD/ [8] ftp://ftp.openpkg.org/release/2.3/UPD/ [9] http://www.openpkg.org/security.html#signature ________________________________________________________________________ For security reasons, this advisory was digitally signed with the OpenPGP public key "OpenPKG " (ID 63C4CB9F) of the OpenPKG project which you can retrieve from http://pgp.openpkg.org and hkp://pgp.openpkg.org.
