Title: Hypermail Message Attachment Buffer Overflow Vulnerability
Severity: HIGH
Description:
Hypermail is a freely available tool for converts email into HTML format.
A buffer overflow vulnerability has been reported for Hypermail. The vulnerability occurs when Hypermail processes emails with overly long attachment names. Specifically, the buffer overflow condition exists in the source file, parse.c, when processing emails.
This vulnerability is only exploitable if Hypermail is configured to output verbose information with the option 'progress = 2'. An attacker can exploit this vulnerability by sending an email with an overly long attachment name, consisting of more than 252 characters, to the vulnerable Hypermail service. The buffer overflow condition will be triggered when Hypermail parses the email and may result in malicious attacker-supplied code being executed by the vulnerable hypermail process.
This vulnerability was reported for Hypermail 2.1.3 to 2.1.5. Other versions may be affected.
