Zero Day Initiative (ZDI) reported a heap buffer overflow
|
|
|
|
|
vulnerability. The vulnerability is due to an incorrect boundary check
|
|
|
|
|
of the user-supplied data prior to copying it to an insufficiently
|
|
|
|
|
sized memory buffer. The flaw occurs when the application attempts to
|
|
|
|
|
handle compressed UPX files.

<impact type="high">

|
|
<p>
|
|
|
|
|
For example by sending a maliciously crafted UPX file into a mail
|
|
|
|
|
server that is integrated with ClamAV, a remote attacker's supplied
|
|
|
|
|
code could be executed with escalated privileges.

There is no known workaround at this time.

All ClamAV users should upgrade to the latest version:
