mutt vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 6.10

Software Description


Race conditions were discovered in mutt’s handling of temporary files.
Under certain conditions when using a shared temp directory (the default), other local users could overwrite arbitrary files owned by the user running mutt. This vulnerability is more likely when the temp directory is over NFS.
