DESCRIPTION:
Michal Zalewski has discovered a weakness in Firefox, which
can
be
exploited by malicious people to cause a DoS (Denial of
Service).
The weakness is caused due to an unspecified error and can
be
exploited to corrupt memory.
Successful exploitation crashes the browser. Execution of
arbitrary
code has not been proven, but can't be completely ruled
out.
The weakness has been confirmed in version 1.5.0.6 for
Windows.
Other
versions may also be affected.
NOTE: Secunia normally doesn't classify a browser crash as
a
vulnerability nor issue an advisory about it. However, the
potential
risc of this issue may be more severe than currently
believed,
which
justifies for an advisory being issued.
SOLUTION:
Do not visit untrusted web sites.
