University Of Washington Pine 4.33

The c-client library in Internet Message Access Protocol (IMAP) dated before 2002 RC2, as used by Pine 4.20 through 4.44, allows remote attackers to cause a denial of service (client crash) via a MIME-encoded email with Content-Type header containing an empty boundary field.

Buffer overflow in PINE before 4.58 allows remote attackers to execute arbitrary code via a malformed message/external-body MIME type.

URL-handling code in Pine 4.43 and earlier allows remote attackers to execute arbitrary commands via a URL enclosed in single quotes and containing shell metacharacters (&).

Pine 4.44 and earlier allows remote attackers to cause a denial of service (core dump and failed restart) via an email message with a From header that contains a large number of quotation marks (").

Pine 4.2.1 through 4.4.4 puts Unix usernames and/or uid into Sender: and X-Sender: headers, which could allow remote attackers to obtain sensitive information.
