The NSURL implementation in the CFNetwork SSL component in Apple iOS before 9 does not properly verify X.509 certificates from SSL servers after a certificate change, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.

Apple iTunes before 11.0.3 does not properly verify X.509 certificates, which allows man-in-the-middle attackers to spoof HTTPS servers via an arbitrary valid certificate.

Improper Verification of Cryptographic Signature vulnerability in Snow Software Inventory Agent on MacOS, Snow Software Inventory Agent on Windows, Snow Software Inventory Agent on Linux allows File Manipulation through Snow Update Packages.This issue affects Inventory Agent: through 6.12.0; Inventory Agent: through 6.14.5; Inventory Agent: through 6.7.2.

This issue was addressed by verifying host keys when connecting to a previously-known SSH server. This issue is fixed in iOS 13.1 and iPadOS 13.1. An attacker in a privileged network position may be able to intercept SSH traffic from the “Run script over SSH” action.

An issue was discovered in Foxit Reader and PhantomPDF before 4.1 on macOS. Because the Hardened Runtime protection mechanism is not applied to code signing, code injection (or an information leak) can occur.

Acrobat Reader DC versions 2020.012.20048 (and earlier), 2020.001.30005 (and earlier) and 2017.011.30175 (and earlier) for macOS are affected by a signature verification bypass that could result in local privilege escalation. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

An issue was discovered on Samsung mobile devices with L(5.0/5.1) and M(6.0) (with Fingerprint support) software. The check of an application's signature can be bypassed during installation. The Samsung ID is SVE-2016-5923 (June 2016).

A PKCS#1 v1.5 signature verification routine in all Android releases from CAF using the Linux kernel may not check padding.

An issue was discovered on Samsung mobile devices with N(7.1), O(8.x), and P(9.0) software. SPENgesture allows arbitrary applications to read or modify user-input logs. The Samsung ID is SVE-2019-14170 (June 2019).

A downgrade issue was addressed with additional code-signing restrictions. This issue is fixed in macOS Sequoia 15.6. An app may be able to access protected user data.

The vulnerability is that IDToken verifier does not verify if token is properly signed. Signature verification makes sure that the token's payload comes from valid provider, not from someone else. An attacker can provide a compromised token with custom payload. The token will pass the validation on the client side. We recommend upgrading to version 1.33.3 or above

The BIG-IP Edge Client Installer on macOS does not follow best practices for elevating privileges during the installation process.  This vulnerability is due to an incomplete fix for CVE-2023-38418.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated

A user can tell curl >= 7.20.0 and <= 7.78.0 to require a successful upgrade to TLS when speaking to an IMAP, POP3 or FTP server (`--ssl-reqd` on the command line or`CURLOPT_USE_SSL` set to `CURLUSESSL_CONTROL` or `CURLUSESSL_ALL` withlibcurl). This requirement could be bypassed if the server would return a properly crafted but perfectly legitimate response.This flaw would then make curl silently continue its operations **withoutTLS** contrary to the instructions and expectations, exposing possibly sensitive data in clear text over the network.

Local privilege escalation due to unrestricted loading of unsigned libraries. The following products are affected: Acronis Agent (macOS) before build 30600, Acronis Cyber Protect 15 (macOS) before build 35979.

Studio Network Solutions ShareBrowser before 7.0 on macOS mishandles signature verification, aka PMP-2636.

Acrobat Reader DC for macOS versions 2020.012.20048 (and earlier), 2020.001.30005 (and earlier) and 2017.011.30175 (and earlier) are affected by a security feature bypass. While the practical security impact is minimal, a defense-in-depth fix has been implemented to further harden the Adobe Reader update process.

An issue was discovered in certain Apple products. macOS before 10.13.4 is affected. The issue involves the "Mail" component. It allows man-in-the-middle attackers to read S/MIME encrypted message content by sending HTML e-mail that references remote resources but lacks a valid S/MIME signature.

An issue in code signature validation was addressed with improved checks. This issue is fixed in macOS Big Sur 11.7, macOS Ventura 13, iOS 16, iOS 15.7 and iPadOS 15.7, macOS Monterey 12.6. An app may be able to bypass code signing checks.

Adobe Acrobat and Reader versions 2019.008.20081 and earlier, 2019.008.20080 and earlier, 2019.008.20081 and earlier, 2017.011.30106 and earlier version, 2017.011.30105 and earlier version, 2015.006.30457 and earlier, and 2015.006.30456 and earlier have a security bypass vulnerability. Successful exploitation could lead to information disclosure.

Little Snitch versions 4.0 to 4.0.6 use the SecStaticCodeCheckValidityWithErrors() function without the kSecCSCheckAllArchitectures flag and therefore do not validate all architectures stored in a fat binary. An attacker can maliciously craft a fat binary containing multiple architectures that may cause a situation where Little Snitch treats the running process as having no code signature at all while erroneously indicating that the binary on disk does have a valid code signature. This could lead to users being confused about whether or not the code signature is valid.

Insufficient consistency checks in signature handling in the networking stack in Google Chrome prior to 58.0.3029.81 for Mac, Windows, and Linux, and 58.0.3029.83 for Android, allowed a remote attacker to incorrectly accept a badly formed X.509 certificate via a crafted HTML page.

In the Android operating system, there is a possible way to replace a boot partition due to improperly used crypto. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android-13Android ID: A-256237041

Local privilege escalation due to unrestricted loading of unsigned libraries. The following products are affected: Acronis Cyber Protect Home Office (macOS) before build 39605, Acronis True Image 2021 (macOS) before build 39287

The Portable Document Format (PDF) specification does not provide any information regarding the concrete procedure of how to validate signatures. Consequently, a Signature Wrapping vulnerability exists in multiple products. An attacker can use /ByteRange and xref manipulations that are not detected by the signature-validation logic. This affects Foxit Reader before 9.4 and PhantomPDF before 8.3.9 and 9.x before 9.4. It also affects eXpert PDF 12 Ultimate, Expert PDF Reader, Nitro Pro, Nitro Reader, PDF Architect 6, PDF Editor 6 Pro, PDF Experte 9 Ultimate, PDFelement6 Pro, PDF Studio Viewer 2018, PDF Studio Pro, PDF-XChange Editor and Viewer, Perfect PDF 10 Premium, Perfect PDF Reader, Soda PDF, and Soda PDF Desktop.

The Portable Document Format (PDF) specification does not provide any information regarding the concrete procedure of how to validate signatures. Consequently, an Incremental Saving vulnerability exists in multiple products. When an attacker uses the Incremental Saving feature to add pages or annotations, Body Updates are displayed to the user without any action by the signature-validation logic. This affects Foxit Reader before 9.4 and PhantomPDF before 8.3.9 and 9.x before 9.4. It also affects LibreOffice, Master PDF Editor, Nitro Pro, Nitro Reader, Nuance Power PDF Standard, PDF Editor 6 Pro, PDFelement6 Pro, PDF Studio Viewer 2018, PDF Studio Pro, Perfect PDF 10 Premium, and Perfect PDF Reader.

Google Chrome before 17.0.963.46 does not properly check signatures, which allows remote attackers to cause a denial of service (application crash) via unspecified vectors.

An issue was discovered in certain Apple products. iOS before 10.3 is affected. macOS before 10.12.4 is affected. The issue involves the "Security" component. It allows remote attackers to bypass intended access restrictions by leveraging a successful result from a SecKeyRawVerify API call with an empty signature.

There is a possible escalation of privilege due to improperly used crypto. This could lead to remote escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

An issue in code signature validation was addressed with improved checks. This issue is fixed in macOS Big Sur 11.3, iOS 14.5 and iPadOS 14.5, watchOS 7.4, tvOS 14.5. A malicious application may be able to bypass Privacy preferences.
