RHSA-2005:397 - Security Advisory

Topic

Updated evolution packages that fix various security issues are now available.

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

Description

Evolution is a GNOME-based collection of personal information management
(PIM) tools.

A bug was found in the way Evolution displays mail messages. It is possible
that an attacker could create a specially crafted mail message that when
opened by a victim causes Evolution to stop responding. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2005-0806 to this issue.

A bug was also found in Evolution's helper program camel-lock-helper. This
bug could allow a local attacker to gain root privileges if
camel-lock-helper has been built to execute with elevated privileges. The
Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned
the name CAN-2005-0102 to this issue. On Red Hat Enterprise Linux,
camel-lock-helper is not built to execute with elevated privileges by
default. Please note however that if users have rebuilt Evolution from the
source RPM, as the root user, camel-lock-helper may be given elevated
privileges.

All users of evolution should upgrade to these updated packages, which
include backported fixes to correct these issues.
