neon - buffer overflow

Stefan Esser discovered a problem in neon, an HTTP and WebDAV client
library. User input is copied into variables not large enough for all
cases. This can lead to an overflow of a static heap variable.

For the stable distribution (woody) this problem has been fixed in
version 0.19.3-2woody5.

For the unstable distribution (sid) this problem has been fixed in
version 0.23.9.dfsg-2 and neon_0.24.6.dfsg-1.

We recommend that you upgrade your libneon* packages.
