Pine versions 4.21 and before contain a buffer overflow vulnerability which allows a remote user to execute arbitrary code on the local client by the sending of a special-crafted email message. The overflow occurs during the periodic "new mail" checking of an open folder. By upgrading to Pine 4.30, users can fix this problem. New pine.tgz and imapd.tgz packages are available for users of Slackware Linux 7.0, 7.1, and -current. ================================================= Pine 4.30 AVAILABLE - (n1/pine.tgz, n1/imapd.tgz) ================================================= The buffer overflow vulnerability that affects Pine 4.21 and earlier can be fixed by upgrading to the new Pine 4.30 packages. The new pine.tgz and imapd.tgz are available in the -current branch: ftp://ftp.slackware.com/pub/slackware/slackware-current/slakware/n1/pine.tgz ftp://ftp.slackware.com/pub/slackware/slackware-current/slakware/n1/imapd.tgz For verification purposes, we provide the following checksums: 16-bit "sum" checksum: 58447 1475 n1/pine.tgz 11458 654 n1/imapd.tgz 128-bit MD5 message digest: 2f7cdbca84e9d3473c74c6cf6ed24b79 n1/pine.tgz 81a5c7373e30357679fe613e38e07a01 n1/imapd.tgz INSTALLATION INSTRUCTIONS FOR THE pine.tgz PACKAGE: --------------------------------------------------- Make sure that no users have Pine running, then issue this command: # upgradepkg pine.tgz INSTALLATION INSTRUCTIONS FOR THE imapd.tgz PACKAGE: --------------------------------------------------- The IMAP and POP3 servers provided by the imapd.tgz package run from inetd. Make sure they are not running. This can be easily accomplished by dropping the machine into single user mode: # telinit 1 Then upgrade the imapd.tgz package: # upgradepkg imapd.tgz Remember, it's also a good idea to backup configuration files before upgrading packages. - Slackware Linux Security Team http://www.slackware.com +------------------------------------------------------------------------+ | HOW TO REMOVE YOURSELF FROM THIS MAILING LIST: | +------------------------------------------------------------------------+ | Send an email to majordomo@slackware.com with this text in the body of | | the email message: | | | | unsubscribe slackware-security | | | | You will get a confirmation message back.
