Subject: [slackware-security] buffer overflow vulnerability in Pine
Date: Thu, 9 Nov 2000 13:21:51 -0800 (PST) |
|
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.
