Summary

Deskflow is a keyboard and mouse sharing app. Prior to continuous build 1.26.0.299, a remote unauthenticated Deskflow server can send kMsgDSetOptions (DSOP) values to ServerProxy::setOptions() in src/lib/client/ServerProxy.cpp so that the value following a modifier option poisons m_modifierTranslationTable, after which ServerProxy::translateKey() or ServerProxy::translateModifierMask() indexes the seven-row s_translationTable or s_masks arrays out of bounds, disclosing four bytes at an attacker-selected relative offset or crashing the connected client; an odd option count also causes an out-of-bounds OptionsList read. This issue is fixed in continuous build 1.26.0.299.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

The maintainers of deskflow/deskflow published their own advisory on GitHub. Reviewed sources take precedence over it.
