Kvirc

KVirc is a narrowly scoped IRC client that, despite its small product footprint, maintains a notable presence among IRC enthusiasts and legacy communication users. Its vulnerability exposure centers on the client application itself and recurs through weakness classes including code injection, improper input validation, path traversal, and format-string handling—typical of an interactive client parsing untrusted network protocol input and user-supplied configuration. The vendor's disclosures have frequently acquired public exploit code, reflecting the accessibility of proof-of-concept development for a focused, open-source application. Current severity, exploitation, and exposure counts are shown alongside this summary.
