GLSA 200803-12: Evolution: Format string vulnerability

Severity:normal
Title:Evolution: Format string vulnerability
Date:03/05/2008
Bugs: #212272
ID:200803-12

Synopsis

A format string error has been discovered in Evolution, possibly resulting in the execution of arbitrary code.

Background

Evolution is a GNOME groupware application.

Affected packages

Package Vulnerable Unaffected Architecture(s)
mail-client/evolution < 2.12.3-r1 >= 2.12.3-r1 All supported architectures

Description

Ulf Harnhammar from Secunia Research discovered a format string error in the emf_multipart_encrypted() function in the file mail/em-format.c when reading certain data (e.g. the "Version:" field) from an encrypted e-mail.

Impact

A remote attacker could entice a user to open a specially crafted encrypted e-mail, potentially resulting in the execution of arbitrary code with the privileges of the user running Evolution.

Workaround

There is no known workaround at this time.

Resolution

All Evolution users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=mail-client/evolution-2.12.3-r1"
