A c-ares regression update has been released for Debian GNU/Linux 8 and 9 Extended LTS to address a regression introduced by the previous update.
ELA-883-2 c-ares regression update
Package : c-ares
Version : 1.10.0-2+deb8u6 (jessie), 1.12.0-1+deb9u5 (stretch)
The previous security update of c-ares, issued as ELA-883-1, causes a regression
on both Jessie and Stretch suites.
This update fixes this regression.
