[GLSA]

Gentoo Linux Security Advisory

Title: Evolution: Format string vulnerabilities (GLSA 200508-12)
Severity: normal
Exploitable: remote
Date: August 23, 2005
Bug(s): #102051
ID: 200508-12

Synopsis


Evolution is vulnerable to format string vulnerabilities which may result
in remote execution of arbitrary code.


Background


Evolution is a GNOME groupware application.


Affected Packages

Package: mail-client/evolution
Vulnerable: < 2.2.3-r3
Unaffected: >= 2.2.3-r3
Architectures: All supported architectures


Description


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
tab (CAN-2005-2550).


Impact


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.


Workaround


There is no known workaround at this time.


Resolution


All Evolution users should upgrade to the latest version:
