A format string error in the "inc_put_error()" function in src/inc.c when displaying a POP3 server's error response can be exploited via specially crafted POP3 server replies containing format specifiers. Successful exploitation may allow execution of arbitrary code, but requires that the user is tricked into connecting to a malicious POP3 server. The vulnerability is confirmed in Sylpheed 2.4.4, Sylpheed-Claws 1.9.100, and Sylpheed-Claws (Claws Mail) 2.10.0. Other versions may also be affected. SOLUTION: Fixed in the SVN and CVS repositories for Sylpheed 2.x and Claws Mail 2.x. Do not connect to untrusted POP3 servers. PROVIDED AND/OR DISCOVERED BY: Ulf Harnhammar, Secunia Research.
