CVSS v3.1 |
| On the first DTLS ClientHello, the parser copies a device-claimed session_id length and validates the
ciphersuite-list length against the total record length instead of the remaining bytes. An unauthenticated
peer drives an OOB source read of up to 255 bytes, and those bytes are echoed verbatim into the outgoing
ServerHello, disclosing adjacent process memory over the network. The crash variant fires on the first
packet. |
| `_nx_icmpv6_validate_options()` scans the option area with `while (length > 2)` (`common/src/nx_icmpv6_validate_options.c:79`). An area whose size leaves a one- or two-byte residue exits the loop with that tail unexamined; the residue is not negative, so the function returns `NX_SUCCESS`. Its zero-length rejection never sees those bytes.
Every consumer then re-walks the same area, reading a two-byte option header at the residue and subtracting `nx_icmpv6_option_length << 3` with no zero check and no remaining-length check. Three outcomes follow, selected by bytes the attacker controls.
**Zero length byte.** The walker subtracts zero and advances zero. All four handlers loop forever — `_nx_icmpv6_process_ra` (`nx_icmpv6_process_ra.c:245, :528`), `_nx_icmpv6_process_ns` (`:251, :329`), `_nx_icmpv6_process_na` (`:147, :156`) and `_nx_icmpv6_process_redirect` (`:247, :350`). The walk runs in the IP thread, which is the highest-priority thread and does not yield inside the loop, so the system stops until a watchdog reset and the frame can be replayed after each one.
**Non-zero length byte on a short residue.** The three unsigned counters underflow — `2 - 8` becomes `0xFFFFFFFA` — and the walk continues past the packet buffer, reading until it faults or meets a zero length byte and freezes. The Router Advertisement counter is signed and exits cleanly in this case.
**One-byte residue.** The walker reads a two-byte option header, over-reading one byte.
During a runaway walk, stray bytes parsing as a link-layer address option are copied into the neighbor cache (`nx_icmpv6_process_ns.c:280, :293`) and subsequently used as the destination MAC for frames to that neighbour, placing off-packet memory on the link. Confirmed by inspection, not reproduced. |
| Use after free in FullScreen in Google Chrome prior to 154.0.8037.92 allowed a remote attacker to execute arbitrary code outside the sandbox via a crafted HTML page. (Chromium security severity: High) |
| U-Boot before 2026.10-rc3 contains an out-of-bounds write vulnerability in read_slotted_partition() that fails to validate image size against partition bounds. Attackers with physical access can supply crafted boot media with oversized headers to write past the load buffer into bootloader memory on devices without Android Verified Boot protection. |

| Improper neutralization of input during web page generation ('cross-site scripting') vulnerability in The Wikimedia Foundation Mediawiki - MassMessage extension allows Stored XSS.
This issue affects Mediawiki - MassMessage extension: before 1.46.1, 1.45.5, 1.43.10. |
| Improper neutralization of input during web page generation ('cross-site scripting') vulnerability in The Wikimedia Foundation Mediawiki - Cargo extension allows Reflected XSS.
This issue affects Mediawiki - Cargo extension: before 1.46.1. |
| An uncontrolled resource consumption vulnerability in the Fireware OS login process (wgagent) allows a remote, unauthenticated attacker to cause a denial of service by sending a specially crafted request. |
| A stack-based buffer overflow vulnerability in the spamBlocker (spamd) service of WatchGuard Fireware OS allows an authenticated attacker with administrator privileges to crash the service or potentially execute arbitrary code by sending a specially crafted management request. |
| An improper authorization vulnerability in WatchGuard Fireware OS's SAML login process allows a remote, authenticated SAML user with access only to the Access Portal to obtain unauthorized Mobile VPN with SSL access through a specially crafted request. |
| A deserialization of untrusted data vulnerability in WatchGuard Fireware OS's SAML single sign-on session handling (samld) allows an attacker who has already obtained the ability to write files on the appliance to execute arbitrary code in the context of the samld service by causing samld to load a maliciously crafted session file. |
| A code injection vulnerability in WatchGuard Fireware OS's BOVPN Over TLS client configuration handling allows an attacker who controls the remote VPN server to execute arbitrary commands as root on the connecting Firebox. |
| A path traversal vulnerability in the Fireware OS WebUI management agent allows an authenticated administrator to read or list arbitrary files on the local filesystem by sending a specially crafted management request. |
| An integer underflow vulnerability in the WatchGuard Fireware OS IKE daemon (iked) allows a remote attacker who has completed the initial IKEv2 handshake to crash the iked process by sending a specially crafted encrypted IKEv2 message, resulting in a denial of service. |
| A missing authorization vulnerability in the wgagent management daemon's session initialization function allows an authenticated, low-privileged user (including a read-only or guest administrator account) to crash the wgagent process and read arbitrary files accessible to the daemon by submitting a specially crafted management API request. |
| An uncontrolled resource consumption vulnerability in Fireware OS's diagnostic tasks feature allows a low-privileged, authenticated user to cause a denial of service of the system's diagnostic tools by repeatedly starting and aborting a specially crafted diagnostic task through the web UI. |
| An improper authorization vulnerability in Fireware OS's Access Portal reverse proxy allows an authenticated, low-privileged Access Portal user to access other web applications they are not authorized for by sending a specially crafted request for a different resource which they are authorized to access. |
| A missing authorization vulnerability in the wgagent management daemon's session initialization function allows an authenticated, low-privileged user (including a read-only or guest administrator account) to crash the wgagent process and read arbitrary files accessible to the daemon by submitting a specially crafted management API request. |
| An integer underflow vulnerability in the WatchGuard Fireware OS IKEv2 daemon (iked) allows a remote, unauthenticated attacker to crash the process by sending a specially crafted encrypted IKEv2 message negotiated with an AES-GCM cipher suite. |
| A NULL pointer dereference vulnerability in Fireware OS's NetFlow packet-processing feature allows a remote, unauthenticated attacker to cause a denial of service by sending a specially crafted IPv6 packet. |
