+ GNU Mailutils is a collection of mail-related utilities, including + an IMAP4 server (imap4d) and a Mail User Agent (mail). +

+
+ +

+ 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). +

+
+ +

+ 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. +

+
+ +

+ There are no known workarounds at this time. +

+
+ +

+ All GNU Mailutils users should upgrade to the latest available + version: +

+ + # emerge --sync + # emerge --ask --oneshot --verbose ">=net-mail/mailutils-0.6-r1" +
