Chris Evans has discovered various integer and stack overflows in libXpm,
|
|
|
|
|
which is shipped as a part of the X Window System. LessTif, an application
|
|
|
|
|
that includes this library, is susceptible to the same issues.

|
A carefully-crafted XPM file could crash applications that are linked
|
|
|
|
|
against libXpm, such as LessTif, potentially allowing the execution of
|
|
|
|
|
arbitrary code with the privileges of the user running the application.

<workaround>
|
|
|
|
|
<p>
|
|
|
|
|
There is no known workaround at this time.

All LessTif users should upgrade to the latest version:
