USN-166-1: Evolution vulnerabilities

Releases

• Ubuntu 5.04
• Ubuntu 4.10

Details

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)
