Metamail PrintHeader non-ASCII characters buffer overflow
| metamail-printheader-nonascii-bo (15247) |  High Risk |
Description:
Metamail is vulnerable to a buffer overflow in the PrintHeader function in the metamail.c file. A remote attacker could create a specially-crafted mail message containing a header with encoded non-ASCI characters and a long character set name to overflow a buffer and execute code on the system with privileges of the user, once the message is opened.
