<background>
|
|
<p>This library provides useful functions commonly found on BSD systems,
|
|
and lacking on others like GNU systems, thus making it easier to port
|
|
projects with strong BSD origins, without needing to embed the same code
|
|
over and over again on each project.

<description>
|
|
<p>libbsd contains a buffer overflow in the fgetwln() function. An if
|
|
statement, which is responsible for checking the necessity to reallocate
|
|
memory in the target buffer, is off by one therefore an out of bounds
|
|
write occurs.
|
|
</p>

|
|
<impact type="normal">
|
|
<p>Remote attackers could potentially execute arbitrary code with the
|
|
privileges of the process.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>There is no known workaround at this time.</p>

</workaround>

<resolution>
|
|
<p>All libbsd users should upgrade to the latest version:</p>

# emerge --ask --verbose --oneshot ">=dev-libs/libbsd-0.8.2"
