Evolution: Format string vulnerability — GLSA 200803-12

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

Affected Packages

mail-client/evolution on all architectures
Affected versions < 2.12.3-r1
Unaffected versions >= 2.12.3-r1

Background

Evolution is a GNOME groupware application.

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"
