Debian LTS Advisory DLA-2515-1 debian-lts@lists.debian.org

Package : csync2
Version : 2.0-8-g175a01c-4+deb9u2
CVE ID : CVE-2019-15523
It was discovered that csync2, a cluster synchronization tool, did
not correctly check for the return value from GnuTLS security
routines. It neglected to repeatedly call this function as required
by the design of the API.
For Debian 9 "Stretch", this problem has been fixed in version
2.0-8-g175a01c-4+deb9u2.
We recommend that you upgrade your csync2 packages.
For the detailed security status of csync2 please refer to
its security tracker page at:
https://security-tracker.debian.org/tracker/csync2
