high Nessus Plugin ID 21439

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The Zero Day Initiative reports :

This vulnerability allows remote attackers to execute arbitrary code on vulnerable Clam AntiVirus installations. Authentication is not required to exploit this vulnerability.

This specific flaw exists within libclamav/upx.c during the unpacking of executable files compressed with UPX. Due to an invalid size calculation during a data copy from the user-controlled file to heap allocated memory, an exploitable memory corruption condition is created.

Solution

Update the affected packages.
