Siemens RuggedCom Rox Uncontrolled Recursion (CVE-2025-9714)

Uncontrolled recursion inXPath evaluationin libxml2 up to and including version 2.9.14 allows a local attacker to cause a stack overflow via crafted expressions. XPath processing functions xmlXPathRunEval, xmlXPathCtxtCompile, and xmlXPathEvalExpr were resetting recursion depth to zero before...

xorg-x11-server: xorg-x11-server-Xwayland: xorg-x11-server: stack buffer overflow in XKB SetMap request via mapWidths indexing

A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. XkbSetMapChecks declares a fixed-size stack buffer mapWidths256 indexed by key type index. The helper function CheckKeyTypes writes to this buffer at a client-controlled offset, allowing a stack buffer overflow. This...

Stack-based Buffer Overflow

Overview Affected versions of this package are vulnerable to Stack-based Buffer Overflow in the rawtoheader function when processing TAR archive headers that contain non-null-terminated name or linkname fields. An attacker can cause a stack buffer overflow and potentially execute arbitrary code o...

xorg-x11-server: xorg-x11-server-Xwayland: xorg-x11-server: stack buffer overflow in XKB key types due to unchecked shift levels

A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. The X server has multiple stack buffers sized XkbMaxShiftLevel XkbNumKbdGroups but CheckKeyTypes does not verify or clamp non-canonical key types to XkbMaxShiftLevel. A client can change key types to excessive shift...

dotnet: ASP.NET Core: Denial of Service via uncontrolled resource consumption

A flaw was found in ASP.NET Core SignalR and Blazor Server. A remote attacker could send a specially crafted MessagePack payload containing deeply nested arrays that trigger excessive recursion and cause a stack overflow. This issue may result in application termination and a denial of service...

CVE-2026-55738

A stack-based buffer overflow exists in the rawtoheader function in src/microtar.c in rxi microtar 0.1.0. The function copies the 100-byte name and linkname fields of a TAR header with strcpy without guaranteeing null termination of the source...

EUVD-2026-37712

A stack-based buffer overflow exists in the rawtoheader function in src/microtar.c in rxi microtar 0.1.0. The function copies the 100-byte name and linkname fields of a TAR header with strcpy without guaranteeing null termination of the source. The POSIX ustar format permits these fixed-width...

CVE-2026-55738 Stack Buffer Overflow in rxi/microtar raw_to_header() via non-null-terminated TAR name field

A stack-based buffer overflow exists in the rawtoheader function in src/microtar.c in rxi microtar 0.1.0. The function copies the 100-byte name and linkname fields of a TAR header with strcpy without guaranteeing null termination of the source...

CVE-2026-55738

The CVE covers a stack-based buffer overflow in rxi/microtar 0.1.0 due to using strcpy() on the 100-byte TAR header name and linkname fields in raw_to_header(). The lack of guaranteed null termination allows reading past the 512-byte header and writing past the destination header buffer, causing ...
