3. Description:

libsoup is an HTTP client/library implementation for GNOME.

A directory traversal flaw was found in libsoup's SoupServer. If an
application used SoupServer to implement an HTTP service, a remote attacker
who is able to connect to that service could use this flaw to access any
local files accessible to that application via a specially-crafted request.
(CVE-2011-2524)

All users of libsoup should upgrade to these updated packages, which
contain a backported patch to resolve this issue. All running applications
using libsoup's SoupServer must be restarted for the update to take effect.
