Changes :

  - Konversation 1.5.1 is a maintenance release containing     only bug fixes. The included changes address several     minor behavioral defects and a low-risk DoS security     defect in the Blowfish ECB support. The KDE Platform     version dependency has increased to v4.9.0 to gain     access to newer Qt socket transport security flags.

  - Fixed a bug causing wildcards in command alias     replacement patterns not to be expanded.

  - Fixed a bug causing auto-joining of channels not     starting in # or & to sometimes fail because the     auto-join command was generated before we got the     CHANTYPES pronouncement by the server.

  - Added a size sanity check for incoming Blowfish ECB     blocks. The blind assumption of incoming blocks being     the expected 12 bytes could lead to a crash or up to 11     byte information leak due to an out-of-bounds read.
    CVE-2014-8483.

  - Enabling SSL/TLS support for connections will now     advertise the protocols Qt considers secure by default,     instead of being hardcoded to TLSv1.

  - Fixed the bundled 'sysinfo' script not coping with empty     lines in /etc/os-release.

  - Made disk space info in the bundled 'sysinfo' script     more robust by forcing the C locale for 'df'.

  - Added an audio player type hint for Cantata to the     bundled 'media' script.

  - Fixed some minor comparison logic errors turned up by     static analysis.

  - Konversation now depends on KDE Platform v4.9.0 or     higher.

An out-of-bounds read vulnerability was discovered in Quassel-core, one of the components of the distributed IRC client Quassel. An attacker can send a crafted message that crash to component causing a denial of services or disclosure of information from process memory.

Konversation developers report :

Konversation's Blowfish ECB encryption support assumes incoming blocks to be the expected 12 bytes. The lack of a sanity-check for the actual size can cause a denial of service and an information leak to the local user.
