RC4 encryption protocol is vulnerable to certain brute force attacks – Opera Security Advisories

Weaknesses in the RC4 encryption protocol have been found, allowing an attacker to deduce the plaintext. If the same message is encrypted many millions of times, statistical methods can be used to extract valuable information, such as cookies. Due to the time this amount of requests takes, this i...

CVE-2013-2566

The RC4 algorithm, as used in the TLS protocol and SSL protocol, has many single-byte biases, which makes it easier for remote attackers to conduct plaintext-recovery attacks via statistical analysis of ciphertext in a large number of sessions that use the same plaintext...

Attack Exploits Weakness in RC4 Cipher to Decrypt User Sessions

It’s been more than 25 years since Ron Rivest invented his RC4 stream cipher, and after all that time it’s still being used widely, which is something of an achievement in the crypto world. However, for more than 15 years researchers have known about a weakness in RC4 that could enable an attacke...

Medium: gnutls

Issue Overview: It was discovered that GnuTLS leaked timing information when decrypting TLS/SSL protocol encrypted records when CBC-mode cipher suites were used. A remote attacker could possibly use this flaw to retrieve plain text from the encrypted packets by using a TLS/SSL server as a padding...

Medium: openssl

Issue Overview: It was discovered that OpenSSL leaked timing information when decrypting TLS/SSL and DTLS protocol encrypted records when CBC-mode cipher suites were used. A remote attacker could possibly use this flaw to retrieve plain text from the encrypted packets by using a TLS/SSL or DTLS...
