Description Mark J. Cox 2003-06-13 13:04:36 UTC 
CAN-2003-0297 found by bugtraq May14

c-client IMAP Client, as used in imap-2002b and Pine 4.53, allows
remote malicious IMAP servers to cause a denial of service (crash) and
possibly execute arbitrary code via certain large (1) literal and (2)
mailbox size values that cause either integer signedness errors or
integer overflow errors.

Not yet investigated impact on Red Hat Linux (does this affect earlier versions
of Pine?).
Comment 1 Mark J. Cox 2004-12-03 10:52:41 UTC 
This affects RHEL2.1 and can allow a remote IMAP server the ability to
crash Pine.

Proposed patch based on code in imap-2002c
Comment 3 Mark J. Cox 2004-12-03 10:54:36 UTC 
I've attached a patch, however there is similar code in
imap_parse_extension that isn't fixed that looks like it could do with
the same fix at first glance (if so then we need to fix imap-2002d as
in RHEL3 as well).
Comment 4 Mark J. Cox 2004-12-14 12:29:17 UTC 
For U7
Comment 6 Mike A. Harris 2004-12-21 11:57:11 UTC 
This issue should now be resolved in pine-4.44-20, currently in
QA testing.  Setting bug to "MODIFIED" state.
