+Description:
+ Stefan Esser discovered [1] a vulnerability within a date parsing
+ function in the Neon HTTP and WebDAV client library [0]. If a special
+ crafted date string is passed to the ne_rfc1036_parse() function it
+ may trigger a sscanf() string overflow into static heap variables.
+ Exploitability heavily depends on the application linked against
+ Neon, but is considered trivial in cases where an out-of-memory
+ condition can be triggered, because the overflowing variable is placed
+ in front of the Neon out-of-memory callback function pointer. The
+ Common Vulnerabilities and Exposures (CVE) project assigned the id
+ CAN-2004-0398 [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-0.24.4-2.0.2.src.rpm
+ ftp> bye
+ $ <prefix>/bin/openpkg rpm -v --checksig neon-0.24.4-2.0.2.src.rpm
+ $ <prefix>/bin/openpkg rpm --rebuild neon-0.24.4-2.0.2.src.rpm
+ $ su -
+ # <prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/neon-0.24.4-2.0.2.*.rpm
+
+ Additionally, perform similar steps for the "subversion", "cadaver",
+ "sitecopy" and "tla" packages.
