Topic

An updated m2crypto package that fixes various bugs is now available for Red Hat
Enterprise Linux 6.

Description

The m2crypto package allows Python programs to call OpenSSL functions.

This updated m2crypto package includes fixes for the following bugs:

  • 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#742914)

  • Prior to this update, the AES_crypt() function did not free a temporary

buffer. This caused a memory leak when the function was called repeatedly. This
problem has been fixed and the AES_crypt() function now frees memory correctly.
(BZ#803520)

  • The implementation of HTTPS connections via a proxy did not reflect the

changes in Python 2.6. Consequently, every attempt to connect to an HTTPS server
using a proxy failed, generating an exception. The M2Crypto implementation has
been updated and now works correctly. (BZ#803554)

All users of m2crypto are advised to upgrade to this updated package, which
fixes these bugs.

Solution

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
