[GLSA-200505-20] Mailutils: Multiple vulnerabilities in imap4d and mail

Vulnerability Assessment Summary
Mailutils: Multiple vulnerabilities in imap4d and mail

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200505-20
(Mailutils: Multiple vulnerabilities in imap4d and mail)


infamous41d discovered several vulnerabilities in GNU Mailutils.
imap4d does not correctly implement formatted printing of command tags
(CVE-2005-1523), fails to validate the range sequence of the "FETCH"
command (CVE-2005-1522), and contains an integer overflow in the
"fetch_io" routine (CVE-2005-1521). mail contains a buffer overflow in
"header_get_field_name()" (CVE-2005-1520).

Impact

A remote attacker can exploit the format string and integer
overflow in imap4d to execute arbitrary code as the imap4d user, which
is usually root. By sending a specially crafted email message, a remote
attacker could exploit the buffer overflow in the "mail" utility to
execute arbitrary code with the rights of the user running mail.
Finally, a remote attacker can also trigger a Denial of Service by
sending a malicious FETCH command to an affected imap4d, causing
excessive resource consumption.

Workaround

There are no known workarounds at this time.
