Signature Verification Bypass

Linux kernel is vulnerable to signature validation bypass attacks. This is because the root can gain direct access to an internal keyring, such as '.dnsresolver' in RHEL-7 or '.builtintrustedkeys' upstream, by joining it as its session keyring.Root user could bypass module signature verification ...

Over Dozen Popular Email Clients Found Vulnerable to Signature Spoofing Attacks

A team of security researchers has discovered several vulnerabilities in various implementations of OpenPGP and S/MIME email signature verification that could allow attackers to spoof signatures on over a dozen of popular email clients. The affected email clients include Thunderbird, Microsoft...

Code injection

A flaw during verification of certain S/MIME signatures causes emails to be shown in Thunderbird as having a valid digital signature, even if the shown message contents aren't covered by the signature. The flaw allows an attacker to reuse a valid S/MIME signature to craft an email message with...
