Kvazaar through 2.3.2 contains an infinite loop vulnerability in read_header() in src/encmain.c that allows attackers to hang the command-line encoder by supplying a truncated Y4M header. Attackers can provide a crafted .y4m file lacking a terminating newline, causing unchecked EOF reads that hang the process indefinitely while consuming a full CPU core.
