CVE-2025-2866 1 Libreoffice 1 Libreoffice 2025-07-03 5.5 Medium
Improper Verification of Cryptographic Signature vulnerability in LibreOffice allows PDF Signature Spoofing by Improper Validation. In the affected versions of LibreOffice a flaw in the verification code for adbe.pkcs7.sha1 signatures could cause invalid signatures to be accepted as valid This issue affects LibreOffice: from 24.8 before < 24.8.6, from 25.2 before < 25.2.2.
CVE-2024-49365 2025-07-03 N/A
tiny-secp256k1 is a tiny secp256k1 native/JS wrapper. Prior to version 1.1.7, a malicious JSON-stringifyable message can be made passing on verify(), when global Buffer is the buffer package. This affects only environments where require('buffer') is the NPM buffer package. Buffer.isBuffer check can be bypassed, resulting in strange objects being accepted as a message, and those messages could trick verify() into returning false-positive true values. This issue has been patched in version 1.1.7.
CVE-2025-24043 1 Microsoft 1 Windbg 2025-07-03 7.5 High
Improper verification of cryptographic signature in .NET allows an authorized attacker to execute code over a network.
CVE-2023-20266 1 Cisco 3 Emergency Responder, Unified Communications Manager, Unity Connection 2025-07-01 6.5 Medium
A vulnerability in Cisco Emergency Responder, Cisco Unified Communications Manager (Unified CM), Cisco Unified Communications Manager Session Management Edition (Unified CM SME), and Cisco Unity Connection could allow an authenticated, remote attacker to elevate privileges to root on an affected device. This vulnerability exists because the application does not properly restrict the files that are being used for upgrades. An attacker could exploit this vulnerability by providing a crafted upgrade file. A successful exploit could allow the attacker to elevate privileges to root. To exploit this vulnerability, the attacker must have valid platform administrator credentials on an affected device.
CVE-2024-36347 2025-07-01 6.4 Medium
Improper signature verification in AMD CPU ROM microcode patch loader may allow an attacker with local administrator privilege to load malicious microcode, potentially resulting in loss of integrity of x86 instruction execution, loss of confidentiality and integrity of data in x86 CPU privileged context and compromise of SMM execution environment.
CVE-2025-32977 2025-06-26 9.6 Critical
Quest KACE Systems Management Appliance (SMA) 13.0.x before 13.0.385, 13.1.x before 13.1.81, 13.2.x before 13.2.183, 14.0.x before 14.0.341 (Patch 5), and 14.1.x before 14.1.101 (Patch 4) allows unauthenticated users to upload backup files to the system. While signature validation is implemented, weaknesses in the validation process can be exploited to upload malicious backup content that could compromise system integrity.
CVE-2024-11696 2 Mozilla, Redhat 9 Firefox, Firefox Esr, Thunderbird and 6 more 2025-06-24 5.4 Medium
The application failed to account for exceptions thrown by the `loadManifestFromFile` method during add-on signature verification. This flaw, triggered by an invalid or unsupported extension manifest, could have caused runtime errors that disrupted the signature validation process. As a result, the enforcement of signature validation for unrelated add-ons may have been bypassed. Signature validation in this context is used to ensure that third-party applications on the user's computer have not tampered with the user's extensions, limiting the impact of this issue. This vulnerability affects Firefox < 133, Firefox ESR < 128.5, Thunderbird < 133, and Thunderbird < 128.5.
CVE-2025-52556 2025-06-23 N/A
rfc3161-client is a Python library implementing the Time-Stamp Protocol (TSP) described in RFC 3161. Prior to version 1.0.3, there is a flaw in the timestamp response signature verification logic. In particular, chain verification is performed against the TSR's embedded certificates up to the trusted root(s), but fails to verify the TSR's own signature against the timestamping leaf certificates. Consequently, vulnerable versions perform insufficient signature validation to properly consider a TSR verified, as the attacker can introduce any TSR signature so long as the embedded leaf chains up to some root TSA. This issue has been patched in version 1.0.3. There is no workaround for this issue.
CVE-2024-42459 3 Elliptic Project, Indutny, Redhat 5 Elliptic, Elliptic, Acm and 2 more 2025-06-20 5.3 Medium
In the Elliptic package 6.5.6 for Node.js, EDDSA signature malleability occurs because there is a missing signature length check, and thus zero-valued bytes can be removed or appended.
CVE-2024-48948 2 Indutny, Nodejs 2 Elliptic, Elliptic 2025-06-20 4.8 Medium
The Elliptic package 6.5.7 for Node.js, in its for ECDSA implementation, does not correctly verify valid signatures if the hash contains at least four leading 0 bytes and when the order of the elliptic curve's base point is smaller than the hash, because of an _truncateToN anomaly. This leads to valid signatures being rejected. Legitimate transactions or communications may be incorrectly flagged as invalid.
CVE-2025-33069 2025-06-20 5.1 Medium
Improper verification of cryptographic signature in App Control for Business (WDAC) allows an unauthorized attacker to bypass a security feature locally.
CVE-2023-25718 1 Connectwise 1 Control 2025-06-19 9.8 Critical
In ConnectWise Control through 22.9.10032 (formerly known as ScreenConnect), after an executable file is signed, additional instructions can be added without invalidating the signature, such as instructions that result in offering the end user a (different) attacker-controlled executable file. It is plausible that the end user may allow the download and execution of this file to proceed. There are ConnectWise Control configuration options that add mitigations.
CVE-2023-42811 2 Aes-gcm Project, Fedoraproject 2 Aes-gcm, Fedora 2025-06-18 4.7 Medium
aes-gcm is a pure Rust implementation of the AES-GCM. Starting in version 0.10.0 and prior to version 0.10.3, in the AES GCM implementation of decrypt_in_place_detached, the decrypted ciphertext (i.e. the correct plaintext) is exposed even if tag verification fails. If a program using the `aes-gcm` crate's `decrypt_in_place*` APIs accesses the buffer after decryption failure, it will contain a decryption of an unauthenticated input. Depending on the specific nature of the program this may enable Chosen Ciphertext Attacks (CCAs) which can cause a catastrophic breakage of the cipher including full plaintext recovery. Version 0.10.3 contains a fix for this issue.
CVE-2023-2030 1 Gitlab 1 Gitlab 2025-06-17 3.5 Low
An issue has been discovered in GitLab CE/EE affecting all versions from 12.2 prior to 16.5.6, 16.6 prior to 16.6.4, and 16.7 prior to 16.7.2 in which an attacker could potentially modify the metadata of signed commits.
CVE-2023-44077 2 Apple, Studionetworksolutions 2 Macos, Sharebrowser 2025-06-17 9.8 Critical
Studio Network Solutions ShareBrowser before 7.0 on macOS mishandles signature verification, aka PMP-2636.
CVE-2025-47827 2025-06-10 8.4 High
In IGEL OS before 11, Secure Boot can be bypassed because the igel-flash-driver module improperly verifies a cryptographic signature. Ultimately, a crafted root filesystem can be mounted from an unverified SquashFS image.
CVE-2022-42010 3 Fedoraproject, Freedesktop, Redhat 4 Fedora, Dbus, Enterprise Linux and 1 more 2025-06-09 6.5 Medium
An issue was discovered in D-Bus before 1.12.24, 1.13.x and 1.14.x before 1.14.4, and 1.15.x before 1.15.2. An authenticated attacker can cause dbus-daemon and other programs that use libdbus to crash when receiving a message with certain invalid type signatures.
CVE-2025-24015 1 Deno 1 Deno 2025-06-09 5.3 Medium
Deno is a JavaScript, TypeScript, and WebAssembly runtime. Versions 1.46.0 through 2.1.6 have an issue that affects AES-256-GCM and AES-128-GCM in Deno in which the authentication tag is not being validated. This means tampered ciphertexts or incorrect keys might not be detected, which breaks the guarantees expected from AES-GCM. Older versions of Deno correctly threw errors in such cases, as does Node.js. Without authentication tag verification, AES-GCM degrades to essentially CTR mode, removing integrity protection. Authenticated data set with set_aad is also affected, as it is incorporated into the GCM hash (ghash) but this too is not validated, rendering AAD checks ineffective. Version 2.1.7 includes a patch that addresses this issue.
CVE-2025-33074 1 Microsoft 1 Azure Functions 2025-06-04 7.5 High
Improper verification of cryptographic signature in Microsoft Azure Functions allows an authorized attacker to execute code over a network.
CVE-2023-5347 1 Korenix 84 Jetnet 4508, Jetnet 4508-w, Jetnet 4508-w Firmware and 81 more 2025-06-03 9.8 Critical
An Improper Verification of Cryptographic Signature vulnerability in the update process of Korenix JetNet Series allows replacing the whole operating system including Trusted Executables. This issue affects JetNet devices older than firmware version 2024/01.
