This update for pidgin to version 2.12.0 fixes the following issues:

This security issue was fixed:
- CVE-2017-2640: Out of bounds memory read in purple_markup_unescape_entity (boo#1028835).

These non-security issues were fixed:
+ libpurple:
  - Fix the use of uninitialised memory if running
    non-debug-enabled versions of glib.
  - Update AIM dev and dist ID's to new ones that were assigned
    by AOL.
  - TLS certificate verification now uses SHA-256 checksums.
  - Fix the SASL external auth for Freenode (boo#1009974).
  - Remove the MSN protocol plugin. It has been unusable and
    dormant for some time.
  - Remove the Mxit protocol plugin. The service was closed at
    the end ofSeptember 2016.
  - Remove the MySpaceIM protocol plugin. The service has been
    defunct for a long time (pidgin.im#15356).
  - Remove the Yahoo! protocol plugin. Yahoo has completely
    reimplemented their protocol, so this version is no longer
    operable as of August 5th, 2016.
  - Remove the Facebook (XMPP) account option. According to
    https://developers.facebook.com/docs/chat the XMPP Chat API
    service ended April 30th, 2015.
  - Fix gnutls certificate validation errors that mainly
    affected Google.
+ General:
  - Replace instances of d.pidgin.im with developer.pidgin.im and
    update the urls to use https (pidgin.im#17036).
+ IRC:
  - Fix an issue of messages being silently cut off at 500
    characters. Large messages are now split into parts and sent
    one by one (pidgin.im#4753).
