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.
