plugins to have more explicit control over login page header
- Added new "smtp_helo_override" hook; allows plugins to override
the HELO host sent to the SMTP server when sending messages
+ - Added PDO support for database connections, so no external
+ database module needs to be installed
+ - Fixed insufficient sendmail command argument escaping (thanks
+ to Mitchel Sahertian, Beyond Security/Dawid Golunski and Filippo
+ Cavallarin for bringing this to our attention). [CVE-2017-7692]
+ - Added ability to control the display of the "Check Spelling"
+ button provided by the squirrelspell plugin, which allows
+ administrators to offer this plugin but keep it out of the way
+ for users who do not want it. Put sqspell_show_button=0 in
+ default preferences if it should be hidden by default
+ - Add ability for saved drafts to indicate if they are a reply
+ or forward and if so, to which message, and mark that message
+ as replied or forwarded when the draft is finally sent
+ - Added option to allow returning to the message one had been
+ replying to after sending
+ - Sanitize user-supplied attachment filenames (thanks to Florian
+ Grunow for reporting this issue) [CVE-2018-8741]
+ - Changed anti-CSRF security token lifetime to be session-based.
+ - Added favicon and ability for admins to use their own by setting
+ $head_tag_extra in config_local.php (see documentation in
+ config/config_local.php)
+ - Updated SVG handling, closing several related vulnerabilities
+ (#2831) [CVE-2018-14950] [CVE-2018-14951] [CVE-2018-14952]
+ [CVE-2018-14953] [CVE-2018-14954] [CVE-2018-14955]
+ - Added IMAP ID command (RFC2971), sent after every login - use
+ by setting $imap_id_command_args in config/config_local.php
+ (see notes in config/config_local.example.php for more details)
+ - Added handling for RCDATA and RAWTEXT elements in HTML sanitizer
+ [CVE-2019-12970]
+ - Added the ability to modify of the value of the global $PHP_SELF
+ variable used throughout the SquirrelMail code (though less so
+ in version 1.5.2). The administrator may do so by adding the
+ configuration settings $php_self_pattern and $php_self_replacement
+ to config/config_local.php, where the pattern should be a full
+ regular expression including the delimiters. This may be helpful
+ when the web server sees traffic from a proxy so the normal
+ $PHP_SELF does not resolve to what it should be for the real client.
+ - Show more accurate filesize for uploaded files and base64-encoded
+ attachments (when reading a message)
+ - Added fixes for PHP version 8 compatibility
Version 1.5.1 (branched on 2006-02-12)
