This bug could allow an attacker to bypass certain access controls by inserting a NUL character into decoded URLs. The Common Vulnerabilities and Exposures (CVE) project assigned the id CAN-2004-0189  to the problem. Please check whether you are affected by running "
/bin/rpm -q squid". If you have the "squid" package installed and its version is affected (see above), we recommend that you immediately upgrade it (see Solution).  Solution: Select the updated source RPM appropriate for your OpenPKG release , fetch it from the OpenPKG FTP service  or a mirror location, verify its integrity , build a corresponding binary RPM from it  and update your OpenPKG installation by applying the binary RPM . 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 squid-2.5.4-2.0.1.src.rpm ftp> bye $ /bin/openpkg rpm -v --checksig squid-2.5.4-2.0.1.src.rpm $ /bin/openpkg rpm --rebuild squid-2.5.4-2.0.1.src.rpm $ su - # /bin/openpkg rpm -Fvh /RPM/PKG/squid-2.5.4-2.0.1.*.rpm ________________________________________________________________________ References:  http://www.squid-cache.org/Advisories/SQUID-2004_1.txt  http://www.squid-cache.org/  http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0189  http://www.openpkg.org/tutorial.html#regular-source  http://www.openpkg.org/tutorial.html#regular-binary  ftp://ftp.openpkg.org/release/1.3/UPD/squid-2.5.3-1.3.1.src.rpm  ftp://ftp.openpkg.org/release/2.0/UPD/squid-2.5.4-2.0.1.src.rpm  ftp://ftp.openpkg.org/release/1.3/UPD/  ftp://ftp.openpkg.org/release/2.0/UPD/  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.
