-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ________________________________________________________________________ OpenPKG Security Advisory The OpenPKG Project http://www.openpkg.org/security.html http://www.openpkg.org email@example.com firstname.lastname@example.org OpenPKG-SA-2004.026 27-May-2004 ________________________________________________________________________ Package: apache (option "with_mod_ssl" only) Vulnerability: arbitrary code execution OpenPKG Specific: no Affected Releases: Affected Packages: Corrected Packages: OpenPKG CURRENT <= apache-1.3.31-20040524 >= apache-1.3.31-20040527 OpenPKG 2.0 <= apache-1.3.29-2.0.1 >= apache-1.3.29-2.0.2 OpenPKG 1.3 <= apache-1.3.28-1.3.3 >= apache-1.3.28-1.3.4 Dependent Packages: none Description: Georgi Guninski discovered  a stack-based buffer overflow in the "SSLOptions +FakeBasicAuth" implementation of Apache's SSL/TLS extension module mod_ssl . The overflow can occur if the Subject-DN in the client certificate exceeds 6KB in length and mod_ssl is configured to trust the issuing CA. The Common Vulnerabilities and Exposures (CVE) project assigned the id CAN-2004-0488  to the problem. Please check whether you are affected by running "
/bin/rpm -q apache" and " /bin/rpm -qi apache | grep with_mod_ssl". If you have the "apache" package with option "with_mod_ssl" installed and its version is affected (see above), we recommend that you immediately upgrade (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 apache-1.3.29-2.0.2.src.rpm ftp> bye $ /bin/openpkg rpm -v --checksig apache-1.3.29-2.0.2.src.rpm $ /bin/openpkg rpm --rebuild --with mod_ssl apache-1.3.29-2.0.2.src.rpm $ su - # /bin/openpkg rpm -Fvh /RPM/PKG/apache-1.3.29-2.0.2.*.rpm ________________________________________________________________________ References:  http://www.modssl.org/  http://lists.netsys.com/pipermail/full-disclosure/2004-May/021610.html  http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0488  http://www.openpkg.org/tutorial.html#regular-source  http://www.openpkg.org/tutorial.html#regular-binary  ftp://ftp.openpkg.org/release/1.3/UPD/apache-1.3.28-1.3.4.src.rpm  ftp://ftp.openpkg.org/release/2.0/UPD/apache-1.3.29-2.0.2.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.
