+ <h1>Problem Description:</h1>
+ <p>The code which handles a close(2) of a descriptor created
+ by posix_openpt(2) fails to undo the configuration which
+ causes SIGIO to be raised. This bug can lead to a
+ write-after-free of kernel memory.</p>
+ <h1>Impact:</h1>
+ <p>The bug permits malicious code to trigger a write-after-free,
+ which may be used to gain root privileges or escape a
+ jail.</p>
