|
|
The Oulu University discovered that bzip2 does not properly check
|
|
offsets provided by the bzip2 file, leading to a buffer overread.

<impact type="normal">
|
|
<p>
|
|
Remote attackers can entice a user or automated system to open a
|
|
specially crafted file that triggers a buffer overread, causing a
|
|
Denial of Service. libbz2 and programs linking against it are also
|
|
affected.
|
|

|
|
<workaround>
|

There is no known workaround at this time.

</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All bzip2 users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=app-arch/bzip2-1.0.5"</code>
