USN-726-2: curl regression
Posted on: 03/06/2009 12:55 AM

A new curl regression update is available for Ubuntu Linux. Here the announcement:

Ubuntu Security Notice USN-726-2 March 04, 2009
curl regression
https://launchpad.net/bugs/337501
==========================
==========================
=========

A security issue affects the following Ubuntu releases:

Ubuntu 8.10

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.

The problem can be corrected by upgrading your system to the
following package versions:

Ubuntu 8.10:
libcurl3 7.18.2-1ubuntu4.3
libcurl3-gnutls 7.18.2-1ubuntu4.3

In general, a standard system upgrade is sufficient to effect the
necessary changes.

Details follow:

USN-726-1 fixed a vulnerability in curl. Due to an incomplete fix, a regres=
sion
was introduced in Ubuntu 8.10 that caused certain types of URLs to fail. Th=
is
update fixes the problem. We apologize for the inconvenience.

Original advisory details:

It was discovered that curl did not enforce any restrictions when followin=
g
URL redirects. If a user or automated system were tricked into opening a U=
RL to
an untrusted server, an attacker could use redirects to gain access to abi=
trary
files. This update changes curl behavior to prevent following "file" URLs =
after
a redirect.


Updated packages for Ubuntu 8.10:
