Evolution 2.0.3 allows remote attackers to cause a denial of service (application crash or hang) via crafted messages, possibly involving charsets in attachment filenames.

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.

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 CVE-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 CVE-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.

Ulf Harnhammar disovered several format string vulnerabilities in Evolution. By tricking an user into viewing a specially crafted vCard attached to an email, specially crafted contact data from an LDAP server, specially crafted task lists from remote servers, or saving Calendar entries with this malicious task list data, it was possible for an attacker to execute arbitrary code with the privileges of the user running Evolution.

In addition, this update fixes a Denial of Service vulnerability in the mail attachment parser. This could be exploited to crash Evolution by tricking an user into opening a malicious email with a specially crafted attachment file name. This does only affect the Ubuntu 4.10 version, the Evolution package shipped with Ubuntu 5.04 is not affected. (CAN-2005-0806).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote Redhat Enterprise Linux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2005:397 advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

It was discovered that certain types of messages could be used to crash the Evolution mail client. Fixes have been applied to correct this behaviour.
