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.
