|
|
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.
|
|
</p>

|
<impact type="normal">
|
|
<p>
|
|
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.
