HTTP2 cleartext service probe Harrison Neal (Dec 24)
Good day,

In instances where HTTP2 is used cleartext without TLS+ALPN (a.k.a., h2c,
prior knowledge), nmap does not appear to have a service probe.

The following is something really simple based on RFC7540, which covers the
initial client message and the server's initial SETTINGS frame. The match
regex below ignores the length (RFC says the server's initial SETTINGS
frame can be empty, nghttpd appears to provide a single entry for...

Steve,

Npcap ought to work with any existing WinPcap wrapper, since the API is
backwards-compatible. I have not used any C# wrappers myself, though I am
aware of SharpPcap (https://github.com/dotpcap/sharppcap) as another.

Npcap Version 1.82 Released with VLAN Tagging and More Gordon Fyodor Lyon (Apr 28)
Dear Nmap Community,

In preparation for an imminent Nmap release (hopefully this week!), we have
released Version 1.82 of our Npcap Windows packet capture and transmission
driver. It builds upon the recent 1.81 release to add support for VLAN
tagging. This allows you to select for packets directed to a certain VLAN
or just inspect the VLAN headers on any packets received. It's especially

Hi,

CVE IDs *can* be assigned for SaaS or similarly "cloud only" software. For a period of time, there was a restriction
that only the provider could make or request such an assignment. But the current CVE rules remove this restriction:

learning) as the sole basis for determining assignment.

RIOT OS 2026.01-devel-317 Stack-Based Buffer Overflow in RIOT ethos Serial Frame Parser Ron E (Jan 10)
A stack-based buffer overflow vulnerability exists in the RIOT OS ethos
utility due to missing bounds checking when processing incoming serial
frame data. The vulnerability occurs in the _handle_char() function, where
incoming frame bytes are appended to a fixed-size stack buffer
(serial->frame) without verifying that the current write index
(serial->framebytes) remains within bounds. An attacker capable of sending
crafted serial or...

RIOT OS 2026.01-devel-317 Stack-Based Buffer Overflow in tapslip6 Utility via Unbounded Device Path Construction Ron E (Jan 10)
A stack-based buffer overflow vulnerability exists in the tapslip6 utility
distributed with RIOT OS (and derived from the legacy uIP/Contiki
networking tools). The vulnerability is caused by unsafe string
concatenation in the devopen() function, which constructs a device path
using unbounded user-controlled input.
Specifically, tapslip6 uses strcpy() and strcat() to concatenate the fixed
prefix "/dev/" with a user-supplied device name...

TinyOS 2.1.2 Stack-Based Buffer Overflow in mcp2200gpio Ron E (Jan 10)
A stack-based buffer overflow vulnerability exists in the mcp2200gpio
utility due to unsafe use of strcpy() and strcat() when constructing device
paths during automatic device discovery. A local attacker can trigger the
vulnerability by creating a specially crafted filename under /dev/usb/,
resulting in stack memory corruption and a process crash. In non-hardened
builds, this may lead to arbitrary code execution.

*Root Cause:*

The vulnerability...

TinyOS 2.1.2 printfUART Global Buffer Overflow via Unbounded Format Expansion Ron E (Jan 10)
A global buffer overflow vulnerability exists in the TinyOS printfUART
implementation used within the ZigBee / IEEE 802.15.4 networking stack. The
issue arises from an unsafe custom sprintf() routine that performs
unbounded string concatenation using strcat() into a fixed-size global
buffer. The global buffer debugbuf, defined with a size of 256 bytes, is
used as the destination for formatted output. When a %s format specifier is
supplied with a...

Panda3d v1.10.16 Uncontrolled Format String in Panda3D egg-mkfont Allows Stack Memory Disclosure Ron E (Jan 05)
Panda3D’s egg-mkfont utility contains an uncontrolled format string
vulnerability that allows disclosure of stack-resident memory. The -gp
(glyph pattern) command-line option allows users to specify a formatting
pattern intended for generating glyph texture filenames. This pattern is
passed directly as the format string to sprintf() without validation or
sanitization. If the supplied pattern contains additional format specifiers
beyond the...

Panda3d v1.10.16 egg-mkfont Stack Buffer Overflow Ron E (Jan 05)
A stack-based buffer overflow vulnerability exists in the Panda3D
egg-mkfont utility due to the use of an unbounded sprintf() call with
attacker-controlled input. By supplying an excessively long glyph pattern
string via the -gp command-line option, an attacker can trigger a stack
buffer overflow, resulting in a deterministic crash of the egg-mkfont
process.

*Technical Details:*
The vulnerability occurs when egg-mkfont constructs output glyph...

Panda3d v1.10.16 deploy-stub Unbounded Stack Allocation Leading to Uninitialized Memory Ron E (Jan 05)
A memory safety vulnerability exists in the Panda3D deploy-stub executable
due to unbounded stack allocation using attacker-controlled input. The
issue allows a local attacker to trigger stack exhaustion and subsequent
use of uninitialized memory during Python interpreter initialization,
resulting in a reliable crash and undefined behavior. The vulnerability is
confirmed by MemorySanitizer (MSAN) as a use-of-uninitialized-value
originating from...

MongoDB v8.3.0 Integer Underflow in LMDB mdb_load Ron E (Jan 05)
This integer underflow vulnerability enables heap metadata corruption and
information disclosure through carefully crafted LMDB dump files.

*Impact:*

- *Information Disclosure*: Heap metadata leak via OOB read

Root Cause:The readline() function fails to validate that the input line
length is non-zero before performing decrement operations, causing integer
underflow. An attacker can craft...

Bioformats v8.3.0 Untrusted Deserialization of Bio-Formats Memoizer Cache Files Ron E (Jan 05)
Bio-Formats performs unsafe Java deserialization of attacker-controlled
memoization cache files (.bfmemo) during image processing. The
loci.formats.Memoizer class automatically loads and deserializes memo files
associated with images without validation, integrity checks, or trust
enforcement.
An attacker can exploit this behavior by supplying a crafted or corrupted
.bfmemo file—either fully attacker-controlled or derived from a legitimate

Bioformats v8.3.0 Improper Restriction of XML External Entity Reference in Bio-Formats Leica Microsystems XML Parser Ron E (Jan 05)
Bio-Formats contains an XML External Entity (XXE) vulnerability in the
Leica Microsystems metadata parsing component. The vulnerability is caused
by the use of an insecurely configured DocumentBuilderFactory when
processing Leica XML-based metadata files (e.g., XLEF). When a crafted XML
file is supplied, the parser allows external entity resolution and external
DTD loading, enabling attackers to trigger arbitrary outbound network
requests, access...

How would one actually move the actual bar in defense? A big part of me

the number of organizations that you can rely on to actually make a

Re: Null Pointer Dereference in HarfBuzz Jacob Bachmeyer (Jan 13)
I am unsure about that:  GCC may have been able to elide the write
because it could prove that the value would never be read, since p is
free()d immediately after the write.  That is different from library
code that returns a newly-constructed object.

Re: Null Pointer Dereference in HarfBuzz Jacob Bachmeyer (Jan 13)
The bug only occurs if allocation returns a NULL pointer in a context
that does not appear to depend on input at all; the attacker does not
get to cause an attempt to allocate HUGE_VALUE here.

If an attacker can craft input such that millions of
"SubtableUnicodesCache" objects are allocated when normal processing
only allocates one, that would be a security issue leading to DoS, but
that is not the bug reported here.

The issue reported here is a write to address zero causing SIGSEGV.  I

Cogent is well known for having incomplete global IPv6 connectivity.

Does your network have a route to 2600::? Does Cogent have a route to
your network? If you're on AS6939, the answer to both of those is
probably "no". Obviously in that case, you're not going to be able to
ping it even if there's a host there listening and willing to respond.

pingability of 2600:: Marco Moock via NANOG (Jan 15)
Hello!

Cogent operates a machine on 2600::. IIRC there was also a route to
sprint for that net, but that seems to be gone.

I can ping that via my ISP (AS8820) that uses Cogent as its current
default uplink.

Although, I cannot ping that from various other ISPs, e.g. HE AS6939 or
DTAG 3320 (no route).

Hi Randy,

/etc/network/interfaces has nothing to do with FRR. I'd try a Debian forum.

are you using the ifupdown package? ifupdown doesn't support the vrrp

FWIW, I get an identical error message from Bookworm. "iface

I have used MapForce Pro edition, a generic commeercial tool for any-to-any data conversion, for similar tasks in the
past. Specifically I was converting pcap logs of SMTP sessions to create a database of source and destination email for
a custom security project. It worked pretty well, and the tool is reasonably priced. I did end up writing a Python pcap

in pcap files into a columnar format like Parquet to enable easy and
