It was discovered that there were several integer overflow issues in Redis, a popular key-value database system. Some BITFIELD-related commands were affected on 32-bit systems.
For Debian 8 Jessie, these problems have been fixed in version 2:2.8.17-1+deb8u8.
We recommend that you upgrade your redis packages.
