CVE-2026-45103

OpenSIPS is a Session Initiation Protocol SIP server implementation. In versions prior to 3.6.6 and 4.0.0-rc1, the TCP message framing layer parses the Content-Length header using unsigned int arithmetic with no overflow check. When an attacker sends a Content-Length value that overflows unsigned...

CVE-2026-16728

A flaw was found in undici. A malicious or faulty upstream server could send a partial response with incorrect length information. When undici's retry interceptor processes this, it may create a response body with a length that does not match the original Content-Length header. This can lead to...

CVE-2026-45538 OpenSIPS: Stack Buffer Overflow in sip_to_json() Header Name Copy

OpenSIPS is a Session Initiation Protocol SIP server implementation. In versions 4.0.0 and prior, processing a SIP message with a header name longer than 255 bytes causes a stack buffer overflow when siptojson is called in the routing script. Function siptojson modules/sipmsgops/sipmsgops.c copie...

CVE-2026-45538

OpenSIPS prior to 4.0.0 is vulnerable to a stack buffer overflow in sip_to_json() when processing a SIP header name longer than 255 bytes. The function copies header names into a fixed 255-byte stack buffer without bounds checking, even though header names can be ~65,000 bytes. A routing script t...

CVE-2026-68743

A flaw was found in SSSD. The extractauthtokv1 function in the PAM responder does not validate the authtokenlength field against the remaining buffer size before processing. A local attacker can exploit this via a crafted protocol v1 request to the PAM responder socket, causing an out-of-bounds...

CVE-2026-68743

SSSD's extract_authtok_v1() in the PAM responder skips validation of auth_token_length against the buffer, allowing a local attacker to trigger an out-of-bounds read and crash via a crafted protocol v1 request. Nessus flags unpatched distros; no in-the-wild exploitation is reported. Apply vendor ...

CVE-2026-68494

The fix released in jackson-core 2.18.6 and 2.21.1 for CVE-2026-18401 GHSA-72hv-8253-57qq, number length constraint bypass in the non-blocking parser is incomplete. This record covers the remaining bypass. The earlier fix wired validateIntegerLength into a new setIntLength helper and invoked it...

CVE-2026-18401

The non-blocking asynchronous JSON parser in jackson-core does not enforce the maxNumberLength constraint defined in StreamReadConstraints default: 1000 characters. An attacker able to submit JSON to an application that uses the async parser API can supply a number token of arbitrary length,...

CVE-2026-68494

This CVE notes an incomplete fix for CVE-2026-18401 in jackson-core’s non-blocking parser, leaving a remaining bypass for number-length constraints when data is streamed in many small chunks. The issue arises in the async parser path (MINOR_NUMBER_INTEGER_DIGITS) where validateIntegerLength() is ...
