Vulnerability Assessment Details

[GLSA-200601-07] ClamAV: Remote execution of arbitrary code

Vulnerability Assessment Summary
ClamAV: Remote execution of arbitrary code

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200601-07
(ClamAV: Remote execution of arbitrary code)

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

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 rights.

Workaround

There is no known workaround at this time.
