Description

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 privileges.

Workaround :

There is no known workaround at this time.
