Upstream has issued an advisory today (April 12):
The issue is fixed upstream in 7.30.0 and with a patch.
The patch is currently checked into Cauldron and Mageia 2 SVN.
Steps to Reproduce:
Patched packages uploaded for Mageia 2 and Cauldron.
Updated curl packages fix security vulnerability:
libcurl is vulnerable to a cookie leak vulnerability when doing requests across
domains with matching tails. This vulnerability can be used to hijack sessions
in targetted attacks since registering domains using a known domain's name as
an ending is trivial (CVE-2013-1944).
