RHBA-2013:0020 - Bug Fix Advisory

Topic

Updated m2crypto packages that fix one bug and add one enhancement are now
available for Red Hat Enterprise Linux 5.

Description

The m2crypto library allows Python programs to call OpenSSL functions.

This update fixes the following bug:

• M2Crypto generated an invalid exception object on SSL timeouts, causing an

IndexError in the Python httplib module. This made it impossible to correctly
handle SSL timeouts in applications. This updated package adds the required
attributes to the SSL timeout exception object and lets httplib process this
information correctly. (BZ#520817)

This update also adds the following enhancement:

• The M2Crypto.httpslib.HTTPSConnection class always created an IPv4 socket.

This made it impossible to connect to IPv6 servers using this class. With this
update, the implementation now correctly creates an IPv4 or IPv6 socket, as
necessary, thus adding support for IPv6 servers. (BZ#761596)

All users of m2crypto are advised to upgrade to these updated packages, which
fix this bug and add this enhancement.
