<impact type="normal">
|
||
|
|
<p>
|
||
|
|
An attacker could exploit these vulnerabilities to cause programs
|
||
|
|
linked against the library to crash or execute arbitrary code with the
|
||
|
|
permissions of the user running the vulnerable program, which could be
|
||
|
|
the root user.
|
||
|
|
</p>
|

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