RHBA-2015:1299 - sendmail bug fix update

Synopsis

sendmail bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated sendmail packages that fix several bugs are now available for Red Hat Enterprise Linux 6.

Description

Sendmail is a Mail Transport Agent (MTA) used to send mail between machines.

This update fixes the following bugs:

  • Previously, the sendmail macro MAXHOSTNAMELEN allowed only 63 characters for the host name length. However, in some cases, it was used against the length of a fully-qualified domain name (FQDN), which has a maximum length of 255 characters. Consequently, FQDN resolution did not work correctly in some cases. To fix this bug, MAXHOSTNAMELEN now allows a maximum of 255 characters. (BZ#640234)

  • The sendmail queue runner could previously terminate unexpectedly under certain circumstances. Consequently, sendmail stopped processing the mail queue. This update introduces a fix that prevents the source code from triggering an assertion in the OpenLDAP code when the connection to an LDAP server is lost while making a query. As a result, the assertion no longer causes the queue runner to terminate, and sendmail continues processing the mail queue as expected. (BZ#837007)

  • Under certain circumstances, sendmail previously recorded a very large number of log messages that reported failures to set the close-on-exec flag. The Milter implementation has been modified to perform socket validation before the fnctl() function attempts to set close-on-exec. As a result, fnctl() is no longer called on invalid sockets, and the described log messages no longer occur. (BZ#845821)

  • Prior to this update, the ldap_routing feature did not work as expected. If ldap_routing was used, sendmail reported the "-T" option missing, and the user was required to insert "-T" manually. With this update, the macro for generating configuration for ldap_routing has been fixed, and the user is no longer required to add "-T" manually when using ldap_routing. (BZ#890227)

  • Previously, the "{client_port}" value could not be used on little-endian machines, for example in mail filters, because it was set incorrectly. This update corrects the "{client_port}" value on little-endian machines. (BZ#1106852)

Users of sendmail are advised to upgrade to these updated packages, which fix these bugs.
