FreeBSD : net-snmp -- fixproc insecure temporary file creation (3e0072d4-d05b-11d9-9aed-000e0c2e438a)

Synopsis :

The remote FreeBSD host is missing a security-related update.

Description :

A Gentoo advisory reports :

Net-SNMP creates temporary files in an insecure manner, possibly
allowing the execution of arbitrary code.

A malicious local attacker could exploit a race condition to change
the content of the temporary files before they are executed by
fixproc, possibly leading to the execution of arbitrary code. A local
attacker could also create symbolic links in the temporary files
directory, pointing to a valid file somewhere on the filesystem. When
fixproc is executed, this would result in the file being overwritten.
