<impact type="normal">
|
|
<p>A remote attacker could send a specially crafted request to trigger a
|
|
use-after-free condition, possibly resulting in arbitrary code execution
|
|
or a Denial of Service condition. Additionally, the bundled version of
|
|
libtommath has an error in its prime number generation, which could
|
|
result in the generation of weak keys.

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