### Summary It's possible for an attacker to construct an XLSX file which links media from external URLs. When opening the XLSX file, PhpSpreadsheet retrieves the image size and type by reading the file contents, if the provided path is a URL. By using specially crafted `php://filter` URLs an attacker can leak the contents of any file or URL. Note that this vulnerability is different from [GHSA-w9xv-qf98-ccq4](https://github.com/PHPOffice/PhpSpreadsheet/security/advisories/GHSA-w9xv-qf98-ccq4), and resides in a different component. ### Details When an XLSX file is opened, the XLSX reader calls `setPath()` with the path provided in the `xl/drawings/_rels/drawing1.xml.rels` file in the XLSX archive: ```php if (isset($images[$embedImageKey])) { // ...omit irrelevant code... } else { $linkImageKey = (string) self::getArrayItem( $blip->attributes('http://schemas.openxmlformats.org/officeDocument/2006/relationships'), 'link' ); if (isset($images[$linkImag...

ABB Cylon Aspect versions 3.08.00 and below suffer from an authenticated OS command injection vulnerability. This can be exploited to inject and execute arbitrary shell commands through the SYSLOG HTTP POST parameter called by the syslogSwitch.php script.

ABB Cylon Aspect versions 3.08.01 and below suffer from an unauthenticated OS command injection vulnerability. This can be exploited to inject and execute arbitrary shell commands through the Footer HTTP POST parameter called by the caldavUtil.php script.

ABB Cylon Aspect versions 3.08.00 and below suffer from an authenticated OS command injection vulnerability. This can be exploited to inject and execute arbitrary shell commands through the timeserver HTTP POST parameter called by the setTimeServer.php script.

ABB Cylon Aspect versions 3.08.01 and below suffer from an unauthenticated arbitrary file disclosure vulnerability. Input passed through the logFile GET parameter via the logYumLookup.php script is not properly verified before being used to download log files. This can be exploited to disclose the contents of arbitrary and sensitive files via directory traversal attacks.

Debian Linux Security Advisory 5786-1 - Integer overflows flaws were discovered in the Compound Document Binary File format parser of libgsf, the GNOME Project G Structured File Library, which could result in the execution of arbitrary code if a specially crafted file is processed.
