Several format string bugs and buffer overflows were discovered in metamail, potentially allowing execution of arbitrary code remotely.
Metamail is a program that decodes MIME encoded mail. It is therefore often automatically called when an email is received or read.
Ulf Harnhammar found two format string bugs and two buffer overflow bugs in Metamail.
A remote attacker could send a malicious email message and execute arbitrary code with the rights of the process calling the Metamail program.
There is no known workaround at this time.
All users of Metamail should upgrade to the latest stable version:
