  about:blank windows used by addons may lead to an attacker being
  able to modify the content of web sites.
• CVE-2007-3845

  and spaces in URIs passed to external programs may allow an attacker
  to pass arbitrary arguments to the helper program if the user is

The Mozilla products in the oldstable distribution (sarge) are no longer
supported with security updates.

For the stable distribution (etch) these problems have been fixed in version
1.5.0.13+1.5.0.14b.dfsg1-0etch1. Builds for hppa will be provided later.

For the unstable distribution (sid) these problems will be fixed soon.

We recommend that you upgrade your icedove packages.
