gitoxide gix-packetline versions before 0.21.5 contain a panic vulnerability in the TextRef implementation that occurs when processing side-band packet lines with empty payloads. A malicious Git server can send a crafted side-band packet to trigger an index out of bounds panic, aborting the client process during fetch operations without authentication.
