Severity: High Title: Mailutils: Multiple vulnerabilities in imap4d and mail Date: May 27, 2005 Bugs: #94053 ID: 200505-20

Synopsis ========
The imap4d server and the mail utility from GNU Mailutils contain multiple vulnerabilities, potentially allowing a remote attacker to execute arbitrary code with root privileges.
Background ==========
GNU Mailutils is a collection of mail-related utilities, including an IMAP4 server (imap4d) and a Mail User Agent (mail).
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-mail/mailutils < 0.6-r1 >= 0.6-r1
Description ===========
infamous41d discovered several vulnerabilities in GNU Mailutils. imap4d does not correctly implement formatted printing of command tags (CAN-2005-1523), fails to validate the range sequence of the "FETCH" command (CAN-2005-1522), and contains an integer overflow in the "fetch_io" routine (CAN-2005-1521). mail contains a buffer overflow in "header_get_field_name()" (CAN-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.
Resolution ==========
All GNU Mailutils users should upgrade to the latest available version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-mail/mailutils-0.6-r1"
