1.  Gentoo Linux Security Advisory

Version Information

Advisory Reference GLSA 200803-12 / evolution
Release Date March 05, 2008
Latest Revision March 05, 2008: 01
Impact normal
Exploitable remote
Package Vulnerable versions Unaffected versions Architecture(s)
mail-client/evolution < 2.12.3-r1 >= 2.12.3-r1 All supported architectures

Related bugreports: #212272


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

2.  Impact Information


Evolution is a GNOME groupware application.


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.


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.

3.  Resolution Information


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-2.12.3-r1"
