Package : remctl
CVE ID : CVE-2018-0493
Santosh Ananthakrishnan discovered a use-after-free in remctl, a server
for Kerberos-authenticated command execution. If the command is
configured with the sudo option, this could potentially result in the
execution of arbitrary code.
The oldstable distribution (jessie) is not affected.
For the stable distribution (stretch), this problem has been fixed in
version 3.13-1+deb9u1.
We recommend that you upgrade your remctl packages.
