WebAug 24, 2016 · Synopsis The remote service supports the use of 64-bit block ciphers. Description The remote host supports the use of a block cipher with 64-bit blocks in one or more cipher suites. It is, therefore, affected by a vulnerability, known as SWEET32, due to the use of weak 64-bit block ciphers. WebStep 1: Review your IBM HTTP Server configuration files (httpd.conf) to determine if the default TLS cipher lists are being used. For each SSLEnable directive, if there is no SSLCipherSpec in the same context, no action is required for Step 1 (3DES is not preferred by default and is not included in the defaults after the fixpacks containing ...
All versions of SSL/TLS. protocol support cipher suites which use DES, 3DES, IDEA or RC2 as the symmetric encryption cipher are affected. IMPACT: Remote attackers can obtain cleartext data via a birthday attack against a long-duration encrypted session. SOLUTION: Disable and stop using DES, 3DES, IDEA or RC2 ciphers.
