See Appendix below for details. Description: According to an OpenSSL [0] security advisory [1], multiple vulnerabilities exist in OpenSSL versions up to and including 0.9.6j and 0.9.7b: 1. Certain ASN.1 encodings that are rejected as invalid by the ASN.1 parser can trigger a bug in the deallocation of the corresponding data structure, corrupting the stack. 2. Unusual ASN.1 tag values can cause an out of bounds read under certain circumstances. 3. A malformed public key in a certificate will crash the verify code if it is set to ignore public key decoding errors (which is usually not the case, except for debugging purposes). 4. Due to an error in the SSL/TLS protocol handling, a server will parse a client certificate when one is not specifically requested. This means that all OpenSSL based SSL/TLS servers can be attacked using vulnerabilities 1, 2 and 3 even if they don't enable client authentication. The Common Vulnerabilities and Exposures (CVE) project assigned the ids CAN-2003-0543 [2], CAN-2003-0544 [3] and CAN-2003-0545 [4] to the problems. Please check whether you are affected by running "/bin/rpm -q openssl". If you have the "openssl" package installed and its version is affected (see above), we recommend that you immediately upgrade it (see Solution) and it's dependent packages (see above), too. [5][6] Solution: Select the updated source RPM appropriate for your OpenPKG release [7][8], fetch it from the OpenPKG FTP service [9][10] or a mirror location, verify its integrity [11], build a corresponding binary RPM from it [5] and update your OpenPKG installation by applying the binary RPM [6]. For the current release OpenPKG 1.3, perform the following operations to permanently fix the security problem (for other releases adjust accordingly). $ ftp ftp.openpkg.org ftp> bin ftp> cd release/1.3/UPD ftp> get openssl-0.9.7b-1.3.2.src.rpm ftp> bye $ /bin/rpm -v --checksig openssl-0.9.7b-1.3.2.src.rpm $ /bin/rpm --rebuild openssl-0.9.7b-1.3.2.src.rpm $ su - # /bin/rpm -Fvh /RPM/PKG/openssl-0.9.7b-1.3.2.*.rpm Additionally, we you have to rebuild and reinstall all dependent packages (see above), too. [5][6] ________________________________________________________________________ Appendix: Some packages are only affected if certain package options ("with_xxx") were used at build time. Please check whether you are affected by running "/bin/rpm -qi ". The table below lists all those packages, their options and values that make up the difference regarding this advisory for OpenPKG CURRENT, 1.3 and 1.2.
