Stefan Esser discovered a vulnerability in the code of the neon library :
if a malicious date string is passed to the ne_rfc1036_parse() function, it
can trigger a string overflow into static heap variables.

Depending on the application linked against libneon and when connected to a
malicious WebDAV server, this vulnerability could allow execution of
arbitrary code with the rights of the user running that application.
