"Two issues have been found in cups, the Common UNIX Printing
System(tm).

Basically both CVEs (CVE-2019-8675 and CVE-2019-8696) are about
stack-buffer-overflow in two functions of libcup. One happens in
asn1_get_type() the other one in asn1_get_packed().

For Debian 8 'Jessie', these problems have been fixed in version
1.7.5-11+deb8u5.

We recommend that you upgrade your cups packages.

block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues.");
