The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - idn in GNU libidn before 1.33 might allow remote attackers to obtain sensitive memory information by reading a zero byte as input, which triggers an out-of-boun...

CVE-2025-27145

copyparty, a portable file server, has a DOM-based cross-site scripting vulnerability in versions prior to 1.16.15. The vulnerability is considered low-risk. By handing someone a maliciously-named file, and then tricking them into dragging the file into copyparty's Web-UI, an attacker could execu...

Cross-site Scripting (XSS)

Overview Affected versions of this package are vulnerable to Cross-site Scripting XSS via the drag-drop action on the Web-UI. An attacker can execute arbitrary JavaScript with the same privileges as the user by tricking them into dragging a maliciously-named, zero-byte file into the interface...

Astra Linux – Vulnerability in libvirt

A flaw was discovered in libvirt. A refactoring of the code that retrieves the list of interfaces for multiple APIs introduced a corner case on platforms where allocating 0 bytes of memory results in a NULL pointer. This corner case could lead to a NULL pointer being dereferenced, causing the...

The vulnerability of the MongoDB database management system lies in improper handling of zero bytes during BSON data processing. This allows attackers to gain unauthorized access to protected information or cause service failures.

The vulnerability of the MongoDB database management system server is related to improper elimination of zero bytes. Exploiting this vulnerability can allow an attacker to gain unauthorized access to protected information or cause service failures by sending specially crafted queries...
