Qualcomm Eudora

Stack-based buffer overflow in Eudora 7.1 allows user-assisted, remote SMTP servers to execute arbitrary code via a long SMTP reply. NOTE: the user must click through a warning about a possible buffer overflow exploit to trigger this issue.

Eudora email client 5.1.1, with "use Microsoft viewer" enabled, allows remote attackers to execute arbitrary programs via an HTML email message containing a META refresh tag that references an embedded .mhtml file with ActiveX controls that execute a second embedded program, which is processed by Internet Explorer.

Eudora 4.x allows remote attackers to bypass the user warning for executable attachments such as .exe, .com, and .bat by using a .lnk file that refers to the attachment, aka "Stealth Attachment."

Eudora before 5.1 allows a remote attacker to execute arbitrary code, when the 'Use Microsoft Viewer' and 'allow executables in HTML content' options are enabled, via an HTML email message containing Javascript, with ActiveX controls and malicious code within IMG tags.

Buffer overflow in Eudora 5.1.1 and 5.0-J for Windows, and possibly other versions, allows remote attackers to execute arbitrary code via a multi-part message with a long boundary string.

Eudora 5.1 allows remote attackers to execute arbitrary code when the "Use Microsoft Viewer" option is enabled and the "allow executables in HTML content" option is disabled, via an HTML email with a form that is activated from an image that the attacker spoofs as a link, which causes the user to execute the form and access embedded attachments.

Eudora 4.1 allows remote attackers to perform a denial of service by sending attachments with long file names.

Buffer overflow in Qualcomm Eudora 7.1.0.9 allows user-assisted, remote IMAP servers to execute arbitrary code via a long FLAGS response to a SELECT INBOX command.

Eudora 5.1 allows remote attackers to bypass security warnings and possibly execute arbitrary code via attachments with names containing a trailing "." (dot).

Buffer overflow in Eudora for Windows 5.2.1, 6.0.3, and 6.1 allows remote attackers to execute arbitrary code via an e-mail with (1) a link to a long URL to the C drive or (2) a long attachment name.

Microsoft HTML control as used in (1) Internet Explorer 5.0, (2) FrontPage Express, (3) Outlook Express 5, and (4) Eudora, and possibly others, allows remote malicious web site or HTML emails to cause a denial of service (100% CPU consumption) via large HTML form fields such as text inputs in a table cell.

The IMAP Client for Sylpheed 0.8.11 allows remote malicious IMAP servers to cause a denial of service (crash) via certain large literal size values that cause either integer signedness errors or integer overflow errors.

Buffer overflow in Eudora 5.2.1 allows remote attackers to cause a denial of service (crash and failed restart) and possibly execute arbitrary code via an Attachment Converted argument with a large number of . (dot) characters.

Eudora 6.1 and 6.0.3 for Windows allows remote attackers to cause a denial of service (crash) via a deeply nested multipart MIME message.

Eudora before 6.1.1 allows remote attackers to cause a denial of service (crash) via an e-mail with a long "To:" field, possibly due to a buffer overflow.

Qualcomm Eudora 5.1 allows remote attackers to execute arbitrary code via an HTML e-mail message that uses a file:// URL in a t:video tag to reference an attached Windows Media Player file containing JavaScript code, which is launched and executed in the My Computer zone by Internet Explorer.

Eudora 6.2.0.14 does not issue a warning when a user forwards an e-mail message that contains base64 or quoted-printable encoded attachments, which makes it easier for remote attackers to read arbitrary files via spoofed "Converted" headers.

Qualcomm Eudora 5.2.1 allows remote attackers to read arbitrary files via an email message with a carriage return (CR) character in a spoofed "Attachment Converted:" string, which is not properly handled by Eudora.

The IMAP Client for Eudora 5.2.1 allows remote malicious IMAP servers to cause a denial of service and possibly execute arbitrary code via certain large literal size values that cause either integer signedness errors or integer overflow errors.

Eudora 5.0.2 allows a remote attacker to read arbitrary files via an email with the path of the target file in the "Attachment Converted" MIME header, which sends the file when the email is forwarded to the attacker by the user.

Eudora mail client includes the absolute path of the sender's host within a virtual card (VCF).

Qualcomm Eudora 5.1.1, 5.2, and possibly other versions stores email attachments in a predictable location, which allows remote attackers to read arbitrary files via a link that loads an attachment with malicious script into a frame, which then executes the script in the local browser context.

Eudora 5.1 and earlier versions stores attachments in a directory with a fixed name, which could make it easier for attackers to exploit vulnerabilities in other software that rely on installing and reading files from directories with known pathnames.

Eudora and Eudora Light before 3.05 allows remote attackers to cause a crash and corrupt the user's mailbox via an e-mail message with certain dates, such as (1) dates before 1970, which cause a Divide By Zero error, or (2) dates that are 100 years after the current date, which causes a segmentation fault.
