form-data requests, causing the creation of a large number of

files uploaded per request. The default value for this new option is
50. See NEWS.Debian for more information.

In the oldstable (etch) distribution, this update also fixes a regression
introduced by the fix for
CVE-2008-5658
in DSA-1789-1 (bug #527560).
For the stable distribution (lenny), these problems have been fixed in
version 5.2.6.dfsg.1-1+lenny4.
The oldstable distribution (etch), these problems have been fixed in
version 5.2.0+dfsg-8+etch16.
For the testing distribution (squeeze) and the unstable distribution
(sid), these problems will be fixed in version 5.2.11.dfsg.1-2.
