Stack-based Buffer Overflow vulnerability in the WatchGuard Agent discovery service on Windows allows Overflow Buffers. An unauthenticated attacker on the same local network could exploit this vulnerability to crash the agent service...

CVE-2026-7900

Heap buffer overflow in ANGLE in Google Chrome prior to 148.0.7778.96 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. Chromium security severity: High...

Buffer Overflow

Overview Affected versions of this package are vulnerable to Buffer Overflow via unsafe string copying in the canonicalization process. An attacker can execute arbitrary code or cause a denial of service by supplying a specially crafted username in the MongoDB URI with authMechanism=GSSAPI before...

BIT-JAVA-2025-6052 Glib: integer overflow in g_string_maybe_expand() leading to potential buffer overflow in glib gstring

A flaw was found in how GLib’s GString manages memory when adding data to strings. If a string is already very large, combining it with more input can cause a hidden overflow in the size calculation. This makes the system think it has enough memory when it doesn’t. As a result, data may be writte...

BIT-JAVA-2025-6021 Libxml2: integer overflow in xmlbuildqname() leads to stack buffer overflow in libxml2

A flaw was found in libxml2's xmlBuildQName function, where integer overflows in buffer size calculations can lead to a stack-based buffer overflow. This issue can result in memory corruption or a denial of service when processing crafted input...
