Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Overread Buffers An adversary attacks a target by providing input that causes an application to read beyond the boundary of a defined buffer. This typically occurs when a value influencing where to start or stop reading is set to reflect positions outside of the valid memory location of the buffer. This type of attack may result in exposure of sensitive information, a system crash, or arbitrary code execution.

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 last seen 2020-06-05 modified 2014-11-13 plugin id 79226 published 2014-11-13 reporter This script is Copyright (C) 2014-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/79226 title openSUSE Security Update : konversation (openSUSE-SU-2014:1406-1) NASL family Fedora Local Security Checks NASL id FEDORA_2014-13837.NASL description Konversation 1.5.1 is a maintenance release containing only bug fixes.
