All supported architectures
Evolution is vulnerable to format string vulnerabilities which may result
in remote execution of arbitrary code.
Evolution is a GNOME groupware application.
Ulf Harnhammar discovered that Evolution is vulnerable to format
string bugs when viewing attached vCards and when displaying contact
information from remote LDAP servers or task list data from remote
servers (CAN-2005-2549). He also discovered that Evolution fails to
handle special calendar entries if the user switches to the Calendars
An attacker could attach specially crafted vCards to emails or
setup malicious LDAP servers or calendar entries which would trigger
the format string vulnerabilities when viewed or accessed from
Evolution. This could potentially result in the execution of arbitrary
code with the rights of the user running Evolution.
There is no known workaround at this time.
All Evolution users should upgrade to the latest version:
Code Listing 3.1: Resolution
# emerge --sync
# emerge --ask --oneshot --verbose ">=mail-client/evolution-2.2.3-r3"
