Name of the Vulnerable Software and Affected Versions Quassel versions prior to 0.12-rc1

Description The issue allows remote attackers to cause a denial of service (crash) via a long CTCP query containing only multibyte characters. This occurs because Quassel uses an incorrect data-type size when splitting a message.

Recommendations For Quassel versions prior to 0.12-rc1, update to version 0.12-rc1 or later to resolve the issue. As a temporary workaround, consider restricting the length of CTCP queries to prevent the denial of service.
