Description: Greuff of VOID.AT discovered various format string vulnerabilities in the error output handling routines of the Neon HTTP and WebDAV client library [1]. The Common Vulnerabilities and Exposures (CVE) project assigned the id CAN-2004-0179 [2] to the problem.

Please check whether you are affected by running "<prefix>/bin/rpm -q neon" (respectively for "subversion", "cadaver", "sitecopy" and "tla"). If you have one of the packages 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][7][8][9], fetch it from the OpenPKG FTP service [11][12] or a mirror location, verify its integrity [13], 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 2.0, 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 neon-0.24.4-2.0.1.src.rpm ftp> bye $ <prefix>/bin/openpkg rpm -v --checksig neon-0.24.4-2.0.1.src.rpm $ <prefix>/bin/openpkg rpm --rebuild neon-0.24.4-2.0.1.src.rpm $ su - # <prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/neon-0.24.4-2.0.1.*.rpm

Additionally, perform similar steps for the "subversion", "cadaver", "sitecopy" and "tla" packages.
