Horde Horde

CVE-2000-0910

Horde library 1.02 allows attackers to execute arbitrary commands via shell metacharacters in the "from" address.

What this means for your business

  • It affects Horde. It matters if your company, or a supplier that handles your data, runs it.
  • An attacker can use it only with access to the machine itself.

What to do

  1. 1Check whether your company or your suppliers run Horde, and which version. The affected versions are listed further down this page.
  2. 2If you do, apply the vendor's fix. A patch or vendor advisory has been published.
