A flaw was found in the interactive shell of the xmllint command-line tool,used for parsing XML files. When a user inputs an overly long command, theprogram does not check the input size properly, which can cause it tocrash. This issue might allow attackers to run harmful code in rareconfigurations without modern protections.
