SB2020092414 - OpenSUSE Linux update for roundcubemail

Description

This security bulletin contains information about 6 secuirty vulnerabilities.

1) Input validation error (CVE-ID: CVE-2019-10740)

The vulnerability allows a remote non-authenticated attacker to manipulate data.

In Roundcube Webmail before 1.3.10, an attacker in possession of S/MIME or PGP encrypted emails can wrap them as sub-parts within a crafted multipart email. The encrypted part(s) can further be hidden using HTML/CSS or ASCII newline characters. This modified multipart email can be re-sent by the attacker to the intended receiver. If the receiver replies to this (benign looking) email, they unknowingly leak the plaintext of the encrypted message part(s) back to the attacker.

2) Cross-site scripting (CVE-ID: CVE-2020-12625)

The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data in "rcube_washtml.php". A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.

3) Path traversal (CVE-ID: CVE-2020-12640)

The vulnerability allows a remote user to perform directory traversal attacks.

The vulnerability exists due to input validation error when processing directory traversal sequences passed via the plugin name to rcube_plugin_api.php. A remote user can send a specially crafted HTTP request and read arbitrary files on the system.

4) Improper Neutralization of Argument Delimiters in a Command (CVE-ID: CVE-2020-12641)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists in rcube_image.php script when processing shell metacharacters in a configuration setting for im_convert_path or im_identify_path. A remote user with ability to change Roundcube Webmail configuration can inject and execute arbitrary OS commands.

5) Cross-site scripting (CVE-ID: CVE-2020-15562)

The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data passed via a crafted HTML e-mail message with a JavaScript payload in the xmlns (aka XML namespace) attribute of a HEAD element when an SVG element exists. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.

6) Cross-site scripting (CVE-ID: CVE-2020-16145)

The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data within HTML messages with malicious svg content or math content. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
