+ <background>
+ <p>
+ neon provides an HTTP and WebDAV client library.

+ </background>
+ <description>
+ <p>
+ 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>
+ </description>
+ <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.
+ </p>
+ </impact>
+ <workaround>
+ <p>
+ There is no known workaround at this time. All users are advised to upgrade
+ to the latest available version of neon.
+ </p>
+ </workaround>
+ <resolution>
+ <p>
+ All users of neon should upgrade to the latest stable version:
+ </p>
+ <code>
+ # emerge sync
+
+ # emerge -pv ">=net-misc/neon-0.24.6"
+ # emerge ">=net-misc/neon-0.24.6"</code>
+ </resolution>
