Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200606-09 (SpamAssassin: Execution of arbitrary code)

When spamd is run with both the '--vpopmail' (-v) and '--paranoid' (-P) options, it is vulnerable to an unspecified issue. Impact :

With certain configuration options, a local or even remote attacker could execute arbitrary code with the rights of the user running spamd, which is root by default, by sending a crafted message to the spamd daemon. Furthermore, the attack can be remotely performed if the '--allowed-ips' (-A) option is present and specifies non-local adresses. Note that Gentoo Linux is not vulnerable in the default configuration. Workaround :

Don't use both the '--paranoid' (-P) and the '--vpopmail' (-v) options.

Solution

All SpamAssassin users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose '>=mail-filter/spamassassin-3.1.3'
