A format string error has been discovered in Sylpheed and Claws Mail, potentially leading to the remote execution of arbitrary code.
|Package||mail-client/sylpheed on all architectures|
|Affected versions||< 2.4.5|

Sylpheed and Claws Mail are two GTK based e-mail clients.
Ulf Harnhammar from Secunia Research discovered a format string error in the inc_put_error() function in file src/inc.c.
A remote attacker could entice a user to connect to a malicious POP server sending specially crafted replies, possibly resulting in the execution of arbitrary code with the privileges of the user running the application.
There is no known workaround at this time.
All Sylpheed users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=mail-client/sylpheed-2.4.5"
All Claws Mail users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=mail-client/claws-mail-3.0.0"
