Bug #80242 [NEW]: imap_mail_compose() segfaults for multipart with rfc822

From: cmb Operating system: * PHP version: 7.3Git-2020-10-15 (Git) Package: IMAP related Bug Type: Bug Bug description:imap_mail_compose() segfaults for multipart with rfc822 Description: ------------ When imap_mail_compose() is used to compose a multipart message with one or more message/rfc822 parts where the subtype is explicitly specified, the function segfaults. Note that composing a multipart message with one or more message/rfc822 where the subtype is not explicitly specified does not segfault, due to the way this is handled by lib-client (2007). Test script: --------------- <?php $bodies = [[ 'type' => TYPEMULTIPART, ], [ 'type' => TYPETEXT, 'contents.data' => 'some text', ], [ 'type' => TYPEMESSAGE, 'subtype' => 'RFC822', ]]; imap_mail_compose([], $bodies); echo "done\n"; ?> Expected result: ---------------- done Actual result: -------------- segfault -- Edit bug report at https://bugs.php.net/bug.php?id=80242&edit=1 -- Fix committed: https://bugs.php.net/fix.php?id=80242&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=80242&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=80242&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=80242&r=needscript Try newer version: https://bugs.php.net/fix.php?id=80242&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=80242&r=support Expected behavior: https://bugs.php.net/fix.php?id=80242&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=80242&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=80242&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=80242&r=globals PHP version support discontinued: https://bugs.php.net/fix.php?id=80242&r=phptooold Daylight Savings: https://bugs.php.net/fix.php?id=80242&r=dst IIS Stability: https://bugs.php.net/fix.php?id=80242&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=80242&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=80242&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=80242&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=80242&r=mysqlcfg
