"The following CVE(s) were reported against src:cups.

CVE-2019-8842

The `ippReadIO` function may under-read an extension field.

CVE-2020-3898

There was a heap based buffer overflow in libcups's ppdFindOption() in
ppd-mark.c. The `ppdOpen` function did not handle invalid UI
constraint. `ppdcSource::get_resolution` function did not handle
invalid resolution strings.

For Debian 8 'Jessie', these problems have been fixed in version
1.7.5-11+deb8u8.

We recommend that you upgrade your cups packages.
