Package : squirrelmail
Vulnerability : several
Problem-Type : remote
Debian-specific: no
CVE ID : CAN-2005-0104 CAN-2005-0152
Debian Bug : 292714 295836

Andrew Archibald discovered that the last update to squirrelmail which
was intended to fix several problems caused a regression which got
exposed when the user hits a session timeout. For completeness below
is the original advisory text:

Several vulnerabilities have been discovered in Squirrelmail, a
commonly used webmail system. The Common Vulnerabilities and
Exposures project identifies the following problems:

CAN-2005-0104

  Upstream developers noticed that an unsanitised variable could
  lead to cross site scripting.

CAN-2005-0152

  Grant Hollingworth discovered that under certain circumstances URL
  manipulation could lead to the execution of arbitrary code with
  the privileges of www-data.  This problem only exists in version
  1.2.6 of Squirrelmail.

For the stable distribution (woody) these problems have been fixed in
version 1.2.6-3.

The correction in the unstable distribution (sid) is not affected by
this regression.

We recommend that you upgrade your squirrelmail package.
