RHSA-2005:267 - Security Advisory

Topic

Updated evolution packages that fix a format string issue are now available.

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

Description

Evolution is the GNOME collection of personal information management (PIM)
tools.

A format string bug was found in Evolution. If a user tries to save a
carefully crafted meeting or appointment, arbitrary code may be executed as
the user running Evolution. The Common Vulnerabilities and Exposures
project has assigned the name CAN-2005-2550 to this issue.

Additionally, several other format string bugs were found in Evolution. If
a user views a malicious vCard, connects to a malicious LDAP server, or
displays a task list from a malicious remote server, arbitrary code may be
executed as the user running Evolution. The Common Vulnerabilities and
Exposures project has assigned the name CAN-2005-2549 to this issue. Please
note that this issue only affects Red Hat Enterprise Linux 4.

All users of Evolution should upgrade to these updated packages, which
contain a backported patch which resolves this issue.
