RHSA-2009:0275 - Security Advisory

标题

Updated imap packages to fix a security issue are now available for Red Hat
Enterprise Linux 3.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

描述

The imap package provides server daemons for both the IMAP (Internet
Message Access Protocol) and POP (Post Office Protocol) mail access protocols.

A buffer overflow flaw was discovered in the dmail and tmail mail delivery
utilities shipped with imap. If either of these utilities were used as a
mail delivery agent, a remote attacker could potentially use this flaw to
run arbitrary code as the targeted user by sending a specially-crafted mail
message to the victim. (CVE-2008-5005)

Users of imap should upgrade to these updated packages, which contain a
backported patch to resolve this issue.
