Kees Cook of Ubuntu discovered that 'KLaola::readBigBlockDepot()' in
|
|
klaola.cc fills 'num_of_bbd_blocks' while reading a .ppt (PowerPoint)
|
|
file without proper sanitizing, resulting in an integer overflow
|
|
subsequently overwriting the heap with parts of the file being read.

<impact type="normal">
|
|
<p>
|
|
By enticing a user to open a specially crafted PowerPoint file, an
|
|
attacker could crash the application and possibly execute arbitrary
|
|
code with the rights of the user running KOffice.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>

<resolution>
|
|
<p>
|
|
All koffice-libs users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=app-office/koffice-libs-1.5.0"</code>
