Vulnerability Title
Deskflow - Unauthenticated server-controlled out-of-bounds read in ServerProxy::setOptions / translateKey modifier-table indexing
Vulnerability Description
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.

Deskflow 缓冲区错误漏洞
Vulnerability Description
Deskflow是Deskflow团队的一款开源键盘鼠标共享软件。 Deskflow 1.26.0.299之前版本存在安全漏洞,该漏洞源于ServerProxy::setOptions()在处理kMsgDSetOptions值时未正确验证选项,导致m_modifierTranslationTable被污染并引发越界读取,可能泄露四个字节数据或导致客户端崩溃。
