"The remote Debian 12 host has a package installed that is affected by multiple vulnerabilities as referenced in the
dsa-5642 advisory.

  - php-svg-lib is an SVG file parsing / rendering library. Prior to version 0.5.1, when parsing the
    attributes passed to a `use` tag inside an svg document, an attacker can cause the system to go to an
    infinite recursion. Depending on the system configuration and attack pattern this could exhaust the memory
    available to the executing process and/or to the server itself. An attacker sending multiple request to a
    system to render the above payload can potentially cause resource exhaustion to the point that the system
    is unable to handle incoming request. Version 0.5.1 contains a patch for this issue. (CVE-2023-50251)

  - php-svg-lib is an SVG file parsing / rendering library. Prior to version 0.5.1, when handling `<use>` tag
    that references an `<image>` tag, it merges the attributes from the `<use>` tag to the `<image>` tag. The
    problem pops up especially when the `href` attribute from the `<use>` tag has not been sanitized. This can
    lead to an unsafe file read that can cause PHAR Deserialization vulnerability in PHP prior to version 8.
    Version 0.5.1 contains a patch for this issue. (CVE-2023-50252)

  - php-svg-lib is a scalable vector graphics (SVG) file parsing/rendering library. Prior to version 0.5.2,
    php-svg-lib fails to validate that font-family doesn't contain a PHAR url, which might leads to RCE on PHP
    < 8.0, and doesn't validate if external references are allowed. This might leads to bypass of restrictions
    or RCE on projects that are using it, if they do not strictly revalidate the fontName that is passed by
    php-svg-lib. The `Style::fromAttributes(`), or the `Style::parseCssStyle()` should check the content of
    the `font-family` and prevents it to use a PHAR url, to avoid passing an invalid and dangerous `fontName`
    value to other libraries. The same check as done in the `Style::fromStyleSheets` might be reused.
    Libraries using this library as a dependency might be vulnerable to some bypass of restrictions, or even
    remote code execution, if they do not double check the value of the `fontName` that is passed by php-svg-
    lib. Version 0.5.2 contains a fix for this issue. (CVE-2024-25117)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
