A logic issue was addressed with improved state management, which may allow a website to track sensitive user information. This issue is related to the WebKitGTK and WPE WebKit modules, and its exploitation can lead to the disclosure of protected information.

O problema está relacionado a um vazamento de informações por canal lateral no DevTools, permitindo que um invasor remoto contorne o isolamento do site por meio de uma página HTML especialmente criada. Isso se deve a erros na criptografia de dados. O invasor pode explorar essa vulnerabilidade para contornar as restrições de segurança existentes.

The issue is related to a logic condition in specific microprocessors that may allow an authenticated user to potentially enable partial physical address information disclosure via local access. It is also associated with a lack of protection for service data. A side-channel attack, similar to DRAM Rowhammer attacks, can be used to steal sensitive data from device memory without directly accessing it. This type of attack allows attackers to read bits from adjacent rows, and it has been demonstrated against OpenSSH, resulting in the extraction of an RSA-2048 key from memory.

The issue is related to the implementation of Intel Software Guard Extensions (SGX) technology and speculative execution in microprocessors. It may allow unauthorized disclosure of information from an enclave to an attacker with local user access via a side-channel analysis. This can enable an attacker to read data from the L1 cache, which may contain fragments of data from the protected area after speculative execution.

The issue makes it easier for attackers to discover a secret key due to not properly considering Curve25519 side-channel attacks, related to files cipher/ecc.c and mpi/ec.c.

The issue is related to a cache side-channel attack that can lead to a complete break of RSA-1024 and potentially RSA-2048 with increased computation. This attack requires the ability to run arbitrary software on the hardware where the private RSA key is used, allowing a local attacker to compromise data confidentiality by fully recovering the RSA key using the left-to-right method for computing the sliding-window expansion.

The issue is related to the MOD EXP CTIME COPY FROM PREBUF function in OpenSSL, which does not properly consider cache-bank access times during modular exponentiation. This makes it easier for local users to discover RSA keys by running a crafted application on the same Intel Sandy Bridge CPU core as a victim and leveraging cache-bank conflicts, also known as a "CacheBleed" attack. The vulnerability allows attackers to recover RSA keys via a side-channel attack.

The issue makes it easier for physically proximate attackers to extract ECDH keys by measuring electromagnetic emanations due to improper elliptic-point curve multiplication during decryption.

The issue is related to a local synchronization problem during RSA decryption in Mbed TLS, allowing a local unprivileged attacker to recover the plaintext of RSA decryption. This affects RSA-without-(EC)DH(E) cipher suites. The vulnerability can be exploited to gain access to protected information.

The issue concerns the lack of ciphertext blinding for Elgamal decryption, allowing physically proximate attackers to obtain the server's private key. This is achieved by determining factors using crafted ciphertext and analyzing the fluctuations in the electromagnetic field during multiplication.

The issue concerns the improper performance of ciphertext normalization and ciphertext randomization in libgcrypt, which can be exploited by physically proximate attackers to conduct key-extraction attacks. This is achieved by collecting voltage data from exposed metal, representing a different attack vector. The vulnerability can lead to a breach of confidentiality of protected information and can be exploited locally.

The issue allows attackers to extract RSA keys via a chosen-ciphertext attack and acoustic cryptanalysis during decryption. This can be exploited remotely and may lead to a violation of the confidentiality and integrity of protected information. The vulnerability is related to the generation of RSA keys using sequences of introductions with certain patterns, which introduces a side channel.
