  • Ubuntu 10.04 LTS
  • Ubuntu 9.10

Software Description

  • mailman


It was discovered that Mailman did not properly sanitize certain fields, resulting in cross-site scripting (XSS) vulnerabilities. With cross-site scripting vulnerabilities, if a user were tricked into viewing server output during a crafted server request, a remote attacker could exploit this to modify the contents, or steal confidential data, within the same domain.
