SSL/TLS: Birthday attack against 64-bit block ciphers (SWEET32)

A flaw was found in the way the DES/3DES cipher was used as part of the TLS/SSL protocol. A man-in-the-middle attacker could use this flaw to recover some plaintext data by capturing large amounts of encrypted traffic between TLS/SSL server and client if the communication used a DES/3DES based...

CVE-2016-6329

OpenVPN, when using a 64-bit block cipher, makes it easier for remote attackers to obtain cleartext data via a birthday attack against a long-duration encrypted session, as demonstrated by an HTTP-over-OpenVPN session using Blowfish in CBC mode, aka a "Sweet32" attack...

CVE-2016-6329

OpenVPN is affected when using 64-bit block ciphers in CBC (e.g., Blowfish). A Sweet32 birthday-attack bound can allow remote attackers to recover partial plaintext on long-lived sessions (e.g., HTTP-over-VPN). The connected advisories recommend upgrading OpenVPN to a newer release to mitigate th...

SA133 : Sweet32 Birthday Attack against DES, 3DES, and Blowfish

SUMMARY Symantec Network ProtectionSy products that use the DES, 3DES, and Blowfish symmetric encryption ciphers in long-lived encrypted SSL/TLS, SSH, or VPN connections are susceptible to the Sweet32 birthday attack. A remote attacker with the ability to observe a long-lived encrypted connection...

MySQL 5.7.x < 5.7.16 Multiple Vulnerabilities (October 2016 CPU) (SWEET32)

The version of MySQL running on the remote host is 5.7.x prior to 5.7.16. It is, therefore, affected by multiple vulnerabilities : - Multiple integer overflow conditions exist in s3srvr.c, sslsess.c, and t1lib.c due to improper use of pointer arithmetic for heap-buffer boundary checks. An...
