    Package        : roundcube
    Version        : 1.4.15+dfsg.1-1+deb11u8
    CVE ID         : not yet available
    Debian Bug     : 1131182 1132268

    Multiple vulnerabilities were discovered in Roundcube, a skinnable AJAX
    based webmail solution for IMAP servers, which might lead to information
    disclosure or privilege escalation.

     * Georgios Tsimpidas discovered an Server-side request forgery (SSRF)
       vulnerability via stylesheet links to a local network hosts.
     * An IMAP injection and CSRF bypass vulnerability was found within the
       email search logic.
     * It was discovered that one could change password without providing
       the old one in some situations.
     * NULL CATHEDRAL discovered that the HTML sanitizer doesn't sanitize
       image sources in SVG `<animate>` attributes.  This allows attackers
       to bypass remote image blocking to track email open action or
       potentially bypass access control.
     * NULL CATHEDRAL discovered that the HTML sanitizer doesn't sanitize
       `<body background=>` attributes.  This allows attackers to bypass
       remote image blocking to track email open action or potentially
       bypass access control.
     * NULL CATHEDRAL discovered that the CSS sanitizer doesn't convert
       `position: fixed` `position: absolute` when `!important` is used.
       This allows an attacker to mask the Roundcube UI with a fake session
       expired page and trick the user into an attacker-controlled login
       page.
     * It was discovered that the HTML sanitizer doesn't sanitize image
       sources in SVG `<animate>` attributes via fill/filter/stroke.  This
       allows attackers to bypass remote image blocking to track email open
       action or potentially bypass access control.
     * A Cross-site scripting (XSS) vulnerability was found in the HTML
       attachment preview.
