Chapter 1. Package Updates
204
This update has been rated as having moderate security impact by the Red Hat Security Response
Team.
Pidgin is an instant messaging program which can log in to multiple accounts on multiple instant
messaging networks simultaneously. The AOL Open System for CommunicAtion in Realtime
(OSCAR) protocol is used by the AOL ICQ and AIM instant messaging systems.
A denial of service flaw was found in the Pidgin OSCAR protocol implementation. If a remote ICQ
user sent a web message to a local Pidgin user using this protocol, it would cause excessive memory
usage, leading to a denial of service (Pidgin crash). (
CVE-2009-1889
1423
)
These updated packages also fix the following bug:
• the Yahoo! Messenger Protocol changed, making it incompatible (and unusable) with Pidgin
versions prior to 2.5.7. This update provides Pidgin 2.5.8, which implements version 16 of the
Yahoo! Messenger Protocol, which resolves this issue.
Note
These packages upgrade Pidgin to version 2.5.8. Refer to the Pidgin release notes for a
full list of changes: http://developer.pidgin.im/wiki/ChangeLog
All Pidgin users should upgrade to these updated packages, which correct these issues. Pidgin must
be restarted for this update to take effect.
1.175.3. RHBA-2009:0407: bug fix update
Note
This update has already been released (prior to the GA of this release) as errata
RHBA-2009:0407
1424
Updated Pidgin packages that fix significant bugs are now available for Red Hat Enterprise Linux 4
and 5.
Pidgin is a multi-protocol Internet Messaging (IM) client.
This update addresses the following bugs:
• the ICQ Internet message protocol servers recently changed and now require clients to use a
newer version of the ICQ protocol. When logging in to ICQ Pidgin 2.5.2 (the version previously
shipped with Red Hat Enterprise Linux 4 and 5) fails with an error message as a result. Pidgin 2.5.5,
included with this update, uses the newer ICQ protocol, which resolves this issue. (

Note
Pidgin 2.5.5 also addresses several other minor bugs. See the
Pidgin 2.5.5
ChangeLog,

for details regarding these other changes.
