PACKAGE : pine
SUMMARY : Remote vulnerabilities
DATE : 2003-09-12 10:15:00
ID : CLA-2003:738
RELEVANT
RELEASES : 7.0, 8, 9

DESCRIPTION
Pine is a mail and news text based client developed by the Washington
University[1].

This update fixes two pine remote vulnerabilities found by
zen-parse[2]. Both vulnerabilities can be exploited by remote
attackers through the sending of specially crafted messages that when
opened by the user can trigger the execution of arbitrary code. The
vulnerabilities are:

1. Buffer overflow in the parsing of the message/external-body type
attribute name/value pairs.

2. Integer overflow in the rfc2231_get_param() function, which is
used to parse e-mails headers.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the names CAN-2003-0720[3] and CAN-2003-0721[4] to these
issues, respectively.


SOLUTION
All pine users should upgrade.
