CVE-2023-6240 is documented as a Marvin vulnerability side-channel leakage in the Linux kernel RSA decryption operation. The connected Nessus entries confirm this CVE is listed among multiple advisories, referencing the same vulnerability block and associating it with Linux Kernel RSA decryption ...

CVE-2023-6240: Observable Discrepancy

A Marvin vulnerability side-channel leakage was found in the RSA decryption operation in the Linux Kernel. This issue may allow a network attacker to decrypt ciphertexts or forge signatures, limiting the services that use that private key...

NewStart CGSL MAIN 6.06 : gnupg2 Vulnerability (NS-SA-2023-0086)

The remote NewStart CGSL host, running version MAIN 6.06, has gnupg2 packages installed that are affected by a vulnerability: - GnuPG through 2.3.6, in unusual situations where an attacker possesses any secret-key information from a victim's keyring and other constraints e.g., use of GPGME are me...

CVE-2023-4421

The NSS code used for checking PKCS1 v1.5 was leaking information useful in mounting Bleichenbacher-like attacks. Both the overall correctness of the padding as well as the length of the encrypted message was leaking through timing side-channel. By sending large number of attacker-selected...

Internet Bug Bounty: OpenSSL vulnerable to the Marvin Attack (CVE-2022-4304)

A timing side channel vulnerability in OpenSSL RSA decryption was discovered that could allow plaintext recovery. By measuring decryption time, an attacker could recover RSA plaintext from captured ciphertexts after a large number of decryption attempts. All RSA padding modes were affected. The...

CVE-2023-49087: Insufficient Verification of Data Authenticity

xml-security is a library that implements XML signatures and encryption. Validation of an XML signature requires verification that the hash value of the related XML-document matches a specific DigestValue-value, but also that the cryptographic signature on the SignedInfo-tree the one that contain...

GHSA-WW7X-3GXH-QM6R Validation of SignedInfo

Validation of an XML Signature requires verification that the hash value of the related XML-document after any optional transformations and/or normalizations matches a specific DigestValue-value, but also that the cryptografic signature on the SignedInfo-tree the one that contains the DigestValue...
