Ulf Harnhammar (Secunia Research) has discovered a format string vulnerability in sylpheed and claws-mail in inc_put_error() function in src/inc.c when displaying POP3 error reply.

Problem can be exploited by malicious POP3 server 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.
