BIT-mariadb-2022-0778 — Infinite loop in BN_mod_sqrt() reachable when parsing certificates

2026-10-02T15:25:49.709544+00:00

Affected: Bitnami: mariadb

The BN_mod_sqrt() function, which computes a modular square root, contains a bug that can cause it to loop forever for non-prime moduli. Internally this function is used when parsing certificates that contain elliptic curve public keys in compressed form or explicit elliptic curve parameters with a base point encoded in compressed form. It is possible to trigger the infinite loop by crafting a certificate that has invalid explicit curve parameters. Since certificate parsing happens prior to verification of the certificate signature, any process that parses an externally supplied certificate may thus be subject to a denial of service attack. The infinite loop can also be reached when parsing crafted private keys as they can contain explicit elliptic curve parameters. Thus vulnerable situations include: - TLS clients consuming server certificates - TLS servers consuming client certificates - Hosting providers taking certificates or private keys from customers - Certificate authorities parsing certification requests from subscribers - Anything else which parses ASN.1 elliptic curve parameters Also any other applications that use the BN_mod_sqrt() where the attacker can control the parameter values are vulnerable to this DoS issue. In the OpenSSL 1.0.2 version the public key is not parsed during initial parsing of the certificate which makes it slightly harder to trigger the infinite loop. However any operation which requires the public key from the certificate will trigger the…

openssl: Infinite loop in BN_mod_sqrt() reachable when parsing certificates

RUSTSEC-2022-0014 — Infinite loop in `BN_mod_sqrt()` reachable when parsing certificates

2026-10-02T15:25:49.709880+00:00

Affected: crates.io: openssl-src

The `BN_mod_sqrt()` function, which computes a modular square root, contains a bug that can cause it to loop forever for non-prime moduli.

Internally this function is used when parsing certificates that contain elliptic curve public keys in compressed form or explicit elliptic curve parameters with a base point encoded in compressed form.

It is possible to trigger the infinite loop by crafting a certificate that has invalid explicit curve parameters.

Since certificate parsing happens prior to verification of the certificate signature, any process that parses an externally supplied certificate may thus be subject to a denial of service attack. The infinite loop can also be reached when parsing crafted private keys as they can contain explicit elliptic curve parameters.

Thus vulnerable situations include:

SCA-2022-0012 — OpenSSL vulnerability affects multiple SICK SIMs

2026-10-02T15:25:49.709910+00:00

In March 2022, the OpenSSL development team disclosed a denial of service in versions "3.0.0," "3.0.1," "1.1.1"-"1.1.1m" and "1.0.2-1.0.2zc" of the OpenSSL library. Exploiting this vulnerability allows remote, unauthenticated attackers to cause an infinite loop. It is possible to trigger the infinite loop by creating a certificate that has invalid explicit curve parameters or when parsing created private keys, as they may contain explicit elliptic curve parameters. It may be possible to put the SIMs in a non-responsive state since 100% of the CPU resource is consumed by the infinite loop calculation. The listed SICK SIM products are currently operated with an OpenSSL version that is vulnerable to CVE-2022-0778. With that it could be possible to exploit the mentioned vulnerability if the SIM devices are connected to a network with untrusted devices. In that case an untrusted client may send a manipulated SSH-certificate to the SIM, which exploits the vulnerability in the OpenSSL library as described above when it comes to the certificate validation by the SIM product. Evaluation is undergoing.

SSA-019200 — SSA-019200: Multiple Vulnerabilities in SCALANCE W-700 IEEE 802.11n Devices Before V6.6.0

2026-10-02T15:25:49.709935+00:00

The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that the A-MSDU flag in the plaintext QoS header field is authenticated. Against devices that support receiving non-SSP A-MSDU frames (which is mandatory as part of 802.11n), an adversary can abuse this to inject arbitrary network packets. An issue was discovered in the kernel in NetBSD 7.1. An Access Point (AP) forwards EAPOL frames to other clients even though the sender has not yet successfully authenticated to the AP. This might be abused in projected Wi-Fi networks to launch denial-of-service attacks against connected clients and makes it easier to exploit other vulnerabilities in connected clients. An issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H. The WEP, WPA, WPA2, and WPA3 implementations accept plaintext frames in a protected Wi-Fi network. An adversary can abuse this to inject arbitrary data frames independent of the network configuration. An issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H. The Wi-Fi implementation does not verify the Message Integrity Check (authenticity) of fragmented TKIP frames. An adversary can abuse this to inject and possibly decrypt packets in WPA or WPA2 networks that support the TKIP data-confidentiality protocol. An issue was discovered in the ALFA Windows 10 driver 1030.36.604 for AWUS036ACH. The WEP, WPA, WPA2, and WPA3 implementations accept fragme…

VDE-2022-013 — PHOENIX CONTACT: Multiple products affected by possible infinite loop within OpenSSL library

2026-10-02T15:25:49.710058+00:00

FL MGUARD and TC MGUARD devices are affected by a possible infinite loop within a OpenSSL library method for parsing elliptic curve parameters. This method is used on parsing cryptographic certificates that contain elliptic curve public keys in compressed form, which may occur on:

Parsing client certificates for HTTPS administrative login Parsing client certificates for SSH administrative login Parsing peer certificates for IPsec VPN connections Parsing certificates of external servers, including: OpenVPN server Configuration pull server Update server Attackers could try to exploit the vulnerability from remote. For the mGuard Device Manager only the mdm Installer for Windows is affected.

UPDATE A: Added FL MGUARD 1102 and FL MGUARD 1105:

On FL MGUARD 1102 and FL MGUARD 1105 with mGuardNT 1.5.2 and older, the device can be affected through an adapted certificate. This can occur on connection with a remote logging server, configured for certificate authentication, or an remote authentication server at certificate based authentication.
