Multiple vendor IRC (Internet Relay Chat) clients command execution

irc-multiple-command-execution (35985) The risk level is classified as MediumMedium Risk

Description:

Multiple vendor IRC (Internet Relay Chat) clients could allow a remote attacker to execute arbitrary IRC commands caused by the improper filtering of id3 tags prior to passing them to XChat. By persuading a victim to play and announce a specially-crafted MP3 file, a remote attacker could exploit this vulnerability to execute arbitrary IRC commands in the victim's IRC client.
