More information:

Several remote vulnerabilities have been discovered in SquirrelMail, a webmail application. The Common Vulnerabilities and Exposures project identifies the following problems:

  • CVE-2009-1578

    Cross site scripting was possible through a number of pages which allowed an attacker to steal sensitive session data.

  • CVE-2009-1579, CVE-2009-1381

    Code injection was possible when SquirrelMail was configured to use the map_yp_alias function to authenticate users. This is not the default.

  • CVE-2009-1580

    It was possible to hijack an active user session by planting a specially crafted cookie into the user's browser.

  • CVE-2009-1581

    Specially crafted HTML emails could use the CSS positioning feature to place email content over the SquirrelMail user interface, allowing for phishing.

For the stable distribution (lenny), these problems have been fixed in version 1.4.15-4+lenny2.
