Package        : libice
Version        : 2:1.0.9-1+deb8u1
CVE ID         : CVE-2017-2626


It has been found, that libice, an X11 Inter-Client Exchange library,
uses weak entropy to generate keys.

Using arc4random_buf() from libbsd should avoid this flaw.


For Debian 8 "Jessie", this problem has been fixed in version
2:1.0.9-1+deb8u1.

We recommend that you upgrade your libice packages.
