Vulnerabilities
Expand / Collapse allThis advisory characterizes the vulnerability differently from the official CVE record. For full details, please see the CSAF document.
The DES and Triple DES ciphers, as used in the TLS, SSH, and IPSec protocols and other protocols and products, have a birthday bound of approximately four billion blocks, which makes it easier for remote attackers to obtain cleartext data via a birthday attack against a long-duration encrypted session, as demonstrated by an HTTPS session using Triple DES in CBC mode, aka a "Sweet32" attack.
Remediation
Update to new version as listed below.
