Description

Music Player Daemon (MPD) before version 0.24.11 contains a CRLF injection vulnerability in the xspf_char_data function within the XSPF playlist plugin that allows attackers to embed literal CR/LF bytes in URI fields by supplying a malicious XSPF playlist with XML numeric character references. Attackers can inject forged key-value lines through the location field into MPD protocol responses including playlistinfo, currentsong, and listplaylist outputs, as well as the state file writer, by exploiting Expat's decoding of numeric character references prior to the character data callback.
