Description
INDI (Instrument Neutral Distributed Interface) indiserver through 2.2.4.2, fixed in commit 96bbd7f, contains a stack buffer overflow vulnerability that allows unauthenticated remote attackers to crash the daemon by sending malformed XML with mismatched tags whose names exceed 1024 bytes. Attackers can send a single TCP packet on port 7624 with mismatched XML tags to trigger an unbounded sprintf() write into a fixed 1024-byte stack buffer in MsgQueue.cpp, terminating the daemon and disrupting all active client and driver sessions.
